Struct midenc_hir::DataSegmentTable

pub struct DataSegmentTable { /* private fields */ }

Similar to [GlobalVariableTable], this structure is used to track data segments in a module or program.

Implementations

impl DataSegmentTable

pub fn is_empty(&self) -> bool

Returns true if the table has no segments defined

pub fn next_available_offset(&self) -> u32

Returns the offset in linear memory where the last data segment ends

pub fn declare( &mut self, offset: Offset, size: u32, init: ConstantData, readonly: bool, ) -> Result<(), DataSegmentError>

Declare a new DataSegment, with the given offset, size, and data.

Returns Err if the declared segment overlaps/conflicts with an existing segment.

pub fn insert( &mut self, segment: Box<DataSegment>, ) -> Result<(), DataSegmentError>

Insert a DataSegment into this table, while preserving the order of the table.

This will fail if the segment is invalid, or overlaps/conflicts with an existing segment.

pub fn iter<'a, 'b: 'a>(&'b self) -> Iter<'a, DataSegmentAdapter>

Traverse the data segments in the table in ascending order by offset

pub fn pop_front(&mut self) -> Option<Box<DataSegment>>

Remove the first data segment from the table

pub fn last(&self) -> Option<&DataSegment>

Return a reference to the last DataSegment in memory

Trait Implementations

impl Clone for DataSegmentTable

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DataSegmentTable

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

Formats the value using the given formatter.

impl Default for DataSegmentTable

fn default() -> DataSegmentTable

Returns the “default value” for a type.
