Enum LabelError 

pub enum LabelError {
    DuplicateLabelInScope(String),
    DuplicateLabelAcrossSiblings(String),
    JumpTargetTooLarge {
        label: String,
        target: usize,
        opcode: String,
    },
}

Error type for label operations

Variants

DuplicateLabelInScope(String)

A label was defined multiple times in the same scope

DuplicateLabelAcrossSiblings(String)

A label is defined in multiple sibling scopes, creating ambiguity

JumpTargetTooLarge

A jump target is too large for the specified opcode

Fields

label: String

The label name

target: usize

The target offset that was too large

opcode: String

The opcode that couldn’t represent the target

Trait Implementations

impl Clone for LabelError

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 LabelError

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

Formats the value using the given formatter.

impl Display for LabelError

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

Formats the value using the given formatter.

impl Eq for LabelError

impl Error for LabelError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

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

Provides type-based access to context intended for error reports.

impl PartialEq for LabelError

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

Equality operator ==.

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

Inequality operator !=.

impl StructuralPartialEq for LabelError

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.
