Struct gimli::read::line::LineRows

pub struct LineRows<R, Program, Offset = <R as Reader>::Offset>
where
    Program: LineProgram<R, Offset>,
    R: Reader<Offset = Offset>,
    Offset: ReaderOffset,
{
    program: Program,
    row: LineRow,
    instructions: LineInstructions<R>,
}

Executes a LineProgram to iterate over the rows in the matrix of line number information.

“The hypothetical machine used by a consumer of the line number information to expand the byte-coded instruction stream into a matrix of line number information.” – Section 6.2.1

Fields

program: Program

row: LineRow

instructions: LineInstructions<R>

Implementations

impl<R, Program, Offset> LineRows<R, Program, Offset>

where Program: LineProgram<R, Offset>, R: Reader<Offset = Offset>, Offset: ReaderOffset,

fn new( program: IncompleteLineProgram<R, Offset>, ) -> LineRows<R, IncompleteLineProgram<R, Offset>, Offset>

fn resume<'program>( program: &'program CompleteLineProgram<R, Offset>, sequence: &LineSequence<R>, ) -> LineRows<R, &'program CompleteLineProgram<R, Offset>, Offset>

pub fn header(&self) -> &LineProgramHeader<R, Offset>

Get a reference to the header for this state machine’s line number program.

pub fn next_row( &mut self, ) -> Result<Option<(&LineProgramHeader<R, Offset>, &LineRow)>>

Parse and execute the next instructions in the line number program until another row in the line number matrix is computed.

The freshly computed row is returned as Ok(Some((header, row))). If the matrix is complete, and there are no more new rows in the line number matrix, then Ok(None) is returned. If there was an error parsing an instruction, then Err(e) is returned.

Unfortunately, the references mean that this cannot be a FallibleIterator.

Trait Implementations

impl<R, Program, Offset> Clone for LineRows<R, Program, Offset>

where Program: LineProgram<R, Offset> + Clone, R: Reader<Offset = Offset> + Clone, Offset: ReaderOffset + Clone,

fn clone(&self) -> LineRows<R, Program, Offset>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<R, Program, Offset> Debug for LineRows<R, Program, Offset>

where Program: LineProgram<R, Offset> + Debug, R: Reader<Offset = Offset> + Debug, Offset: ReaderOffset + Debug,

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

Formats the value using the given formatter.
