Struct llvm_mapper::unroll::UnrolledBlock

pub struct UnrolledBlock {
    pub id: BlockId,
    // some fields omitted
}

A fully unrolled block within the bitstream, with potential records and sub-blocks.

Fields

id: BlockId

This block’s ID.

Implementations

impl UnrolledBlock

pub fn maybe_one_record(
    &self,
    code: u64
) -> Result<Option<&UnrolledRecord>, BlockMapError>

Get zero or one records from this block by the given record code.

Returns an error if the block has more than one record for this code.

pub fn one_record(&self, code: u64) -> Result<&UnrolledRecord, BlockMapError>

Get a single record from this block by its record code.

Returns an error if the block either lacks an appropriate record or has more than one.

pub fn records(&self, code: u64) -> impl Iterator<Item = &UnrolledRecord> + '_

Return an iterator for all records that share the given code. Records are iterated in the order of insertion.

The returned iterator is empty if the block doesn’t have any matching records.

pub fn all_records(&self) -> impl Iterator<Item = &UnrolledRecord> + '_

Return an iterator over all records in the block, regardless of their codes. Records are iterated in the order of insertion.

This is useful in contexts where the mapper’s behavior does not vary significantly by record code, such as within the type table mapper.

pub fn blocks(&self, id: BlockId) -> impl Iterator<Item = &UnrolledBlock> + '_

Return an iterator over all sub-blocks within this block that share the given ID.

The returned iterator is empty if the block doesn’t have any matching sub-blocks.

pub fn maybe_one_block(
    &self,
    id: BlockId
) -> Result<Option<&UnrolledBlock>, BlockMapError>

Get zero or one sub-blocks from this block by the given block ID.

Returns an error if the block has more than one matching sub-block.

pub fn one_block(&self, id: BlockId) -> Result<&UnrolledBlock, BlockMapError>

Get a single sub-block from this block by its block ID.

Returns an error if the block either lacks an appropriate block or has more than one.
