Struct stable_mir::mir::body::VarDebugInfo

pub struct VarDebugInfo {
    pub name: Symbol,
    pub source_info: SourceInfo,
    pub composite: Option<VarDebugInfoFragment>,
    pub value: VarDebugInfoContents,
    pub argument_index: Option<u16>,
}

Debug information pertaining to a user variable.

Fields

name: Symbol

The variable name.

source_info: SourceInfo

Source info of the user variable, including the scope within which the variable is visible (to debuginfo).

composite: Option<VarDebugInfoFragment>

The user variable’s data is split across several fragments, each described by a VarDebugInfoFragment.

value: VarDebugInfoContents

Where the data for this user variable is to be found.

argument_index: Option<u16>

When present, indicates what argument number this variable is in the function that it originated from (starting from 1). Note, if MIR inlining is enabled, then this is the argument number in the original function before it was inlined.

Implementations

impl VarDebugInfo

pub fn local(&self) -> Option<Local>

Return a local variable if this info is related to one.

pub fn constant(&self) -> Option<&ConstOperand>

Return a constant if this info is related to one.

Trait Implementations

impl Clone for VarDebugInfo

fn clone(&self) -> VarDebugInfo

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for VarDebugInfo

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

Formats the value using the given formatter.

impl PartialEq for VarDebugInfo

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Eq for VarDebugInfo

impl StructuralPartialEq for VarDebugInfo

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.
