Enum Bytes 

pub enum Bytes {
    Raw(String),
    JumpPlaceholder(JumpPlaceholderData),
    CircularCodesizePlaceholder(CircularCodesizePlaceholderData),
    ArgsStartPlaceholder(AstSpan),
    AssertPcPlaceholder(AssertPcPlaceholderData),
}

Bytecode with different types for placeholders

Variants

Raw(String)

Raw bytecode - ready to use

JumpPlaceholder(JumpPlaceholderData)

Jump placeholder - “xxxx” needs label resolution

CircularCodesizePlaceholder(CircularCodesizePlaceholderData)

Circular codesize placeholder - “cccc” for self-referential __codesize

ArgsStartPlaceholder(AstSpan)

__argsstart() placeholder - a PUSH2 filled with the offset of the constructor arguments, with the span of the call for errors outside the constructor

AssertPcPlaceholder(AssertPcPlaceholderData)

Assert PC placeholder - validates program counter after jump relaxation

Implementations

impl Bytes

pub fn as_str(&self) -> String

Get the underlying hex string (generates it for placeholders)

pub fn to_hex(&self) -> String

Convert to hex representation (same as as_str but more explicit name)

pub fn len(&self) -> usize

Get the length in bytes (not hex characters) Each pair of hex characters represents one byte

pub fn is_empty(&self) -> bool

Check if the bytecode is empty

Trait Implementations

impl Clone for Bytes

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 Bytes

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

Formats the value using the given formatter.

impl Display for Bytes

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

Formats the value using the given formatter.

impl Eq for Bytes

impl Ord for Bytes

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for Bytes

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Bytes

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

Layout

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.
