Struct InputFunctions

pub struct InputFunctions {
    prepare_input: FunctionIdx,
    pub assert_input_args_wf: FunctionIdx,
    pub utf8_is_boundary: Option<FunctionIdx>,
    pub start_config: FunctionIdx,
}

Holds indices to WebAssembly functions related to input processing.

These functions are used by the compiled regex to manage and interpret the input haystack.

Fields

prepare_input: FunctionIdx

assert_input_args_wf: FunctionIdx

utf8_is_boundary: Option<FunctionIdx>

start_config: FunctionIdx

Implementations

impl InputFunctions

pub fn new( ctx: &mut CompileContext, input_layout: &InputLayout, pattern_lookup_start: FunctionIdx, ) -> Self

Creates and registers the necessary WebAssembly functions for input handling.

This includes functions for preparing input memory, asserting argument well-formedness, checking UTF-8 boundaries, and configuring start conditions.

fn start_config_fn( nfa: &NFA, pattern_lookup_start: FunctionIdx, pattern_lookup_start_result_block_sig: TypeIdx, ) -> Function

fn utf8_is_boundary_fn() -> Function

fn assert_input_args_wf_fn( page_size: usize, input_layout: &InputLayout, ) -> Function

fn prepare_input_fn(page_size: usize, input_layout: &InputLayout) -> Function

Trait Implementations

impl Debug for InputFunctions

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

Formats the value using the given formatter.
