Struct walrus::CodeTransform

pub struct CodeTransform {
    pub instruction_map: Vec<(InstrLocId, usize)>,
    pub code_section_start: usize,
    pub function_ranges: Vec<(Id<Function>, Range)>,
}

Code transformation records, which is used to transform DWARF debug entries.

Fields

instruction_map: Vec<(InstrLocId, usize)>

Maps from an offset of an instruction in the input Wasm to its offset in the output Wasm.

Note that an input offset may be mapped to multiple output offsets, and vice versa, due to transformations like function inlinining or constant propagation.

code_section_start: usize

Offset of code section from the front of Wasm binary

function_ranges: Vec<(Id<Function>, Range)>

Emitted binary ranges of functions

Trait Implementations

impl Debug for CodeTransform

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

Formats the value using the given formatter.

impl Default for CodeTransform

fn default() -> CodeTransform

Returns the “default value” for a type.
