Struct SourceMapEntry 

pub struct SourceMapEntry {
    pub ic: usize,
    pub pc: usize,
    pub bytecode_length: usize,
    pub source_start: usize,
    pub source_length: usize,
    pub file_id: u32,
}

A bytecode source mapping entry

Fields

ic: usize

Instruction Counter (IC) - the instruction index (0, 1, 2, …) This is used to index into the source map array

pc: usize

Program Counter (PC) - the byte offset in the bytecode where this instruction starts For example: if PUSH1 0x42 starts at byte 0, PC = 0

bytecode_length: usize

Length of the bytecode segment for this instruction (in bytes) For example: PUSH1 0x42 = 2 bytes, PUSH0 = 1 byte, SSTORE = 1 byte

source_start: usize

Start position in the source file (character offset)

source_length: usize

Length of the source code that generated this instruction (in characters) This is NOT the bytecode length, but the source text length

file_id: u32

File ID for multi-file support (0 for main file, 1+ for includes)

Implementations

impl SourceMapEntry

pub fn generate_solidity_source_map(entries: &[SourceMapEntry]) -> String

Generate a Solidity-compatible source map from a vector of SourceMapEntry

Solidity format: “s:l:f:j” where:

• s = source start position
• l = length in source (end - start)
• f = source file index (0 for single file)
• j = jump type (i/o/- for into/out/regular)

Multiple entries separated by semicolons, with omitted values if same as previous

Trait Implementations

impl Clone for SourceMapEntry

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SourceMapEntry

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for SourceMapEntry

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for SourceMapEntry

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for SourceMapEntry

impl From<SourceMapEntry> for JsValue

where SourceMapEntry: Serialize,

fn from(value: SourceMapEntry) -> Self

Converts to this type from the input type.

impl FromWasmAbi for SourceMapEntry

where Self: DeserializeOwned,

type Abi = <JsType as FromWasmAbi>::Abi

The Wasm ABI type that this converts from when coming back out from the ABI boundary.

unsafe fn from_abi(js: Self::Abi) -> Self

Recover a Self from Self::Abi.

impl IntoWasmAbi for &SourceMapEntry

where SourceMapEntry: Serialize,

type Abi = <JsType as IntoWasmAbi>::Abi

The Wasm ABI type that this converts into when crossing the ABI boundary.

fn into_abi(self) -> Self::Abi

Convert self into Self::Abi so that it can be sent across the wasm ABI boundary.

impl IntoWasmAbi for SourceMapEntry

where SourceMapEntry: Serialize,

type Abi = <JsType as IntoWasmAbi>::Abi

The Wasm ABI type that this converts into when crossing the ABI boundary.

fn into_abi(self) -> Self::Abi

Convert self into Self::Abi so that it can be sent across the wasm ABI boundary.

impl OptionFromWasmAbi for SourceMapEntry

where Self: DeserializeOwned,

fn is_none(js: &Self::Abi) -> bool

Tests whether the argument is a “none” instance. If so it will be deserialized as None, and otherwise it will be passed to FromWasmAbi.

impl OptionIntoWasmAbi for SourceMapEntry

where SourceMapEntry: Serialize,

fn none() -> Self::Abi

Returns an ABI instance indicating “none”, which JS will interpret as the None branch of this option.

impl PartialEq for SourceMapEntry

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl RefFromWasmAbi for SourceMapEntry

where Self: DeserializeOwned,

type Abi = <JsType as RefFromWasmAbi>::Abi

The Wasm ABI type references to Self are recovered from.

type Anchor = SelfOwner<SourceMapEntry>

The type that holds the reference to Self for the duration of the invocation of the function that has an &Self parameter. This is required to ensure that the lifetimes don’t persist beyond one function call, and so that they remain anonymous.

unsafe fn ref_from_abi(js: Self::Abi) -> Self::Anchor

Recover a Self::Anchor from Self::Abi.

impl Serialize for SourceMapEntry

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
