Struct CraneliftDebugInfo 

pub struct CraneliftDebugInfo {
    pub source_file: Option<String>,
    pub source_function: Option<String>,
    pub location_map: Vec<(usize, u32, u32)>,
    pub var_names: HashMap<String, String>,
}

Debug information attached to a Cranelift function.

Fields

source_file: Option<String>

Source file name.

source_function: Option<String>

Source function name (may differ from IR name).

location_map: Vec<(usize, u32, u32)>

Mapping from instruction offset to (line, column) in source.

var_names: HashMap<String, String>

Local variable names: (ir_value, source_name).

Implementations

impl CraneliftDebugInfo

pub fn new( source_file: impl Into<String>, source_function: impl Into<String>, ) -> Self

Create a new debug info record.

pub fn add_location(&mut self, offset: usize, line: u32, column: u32)

Record a source location for an instruction.

pub fn add_var_name( &mut self, ir_name: impl Into<String>, source_name: impl Into<String>, )

Record a variable name mapping.

pub fn emit_comments(&self) -> String

Emit debug info as comments.
