Struct ParserOptions 

#[non_exhaustive]
pub struct ParserOptions {
    pub optimize_local_memory_allocation: bool,
    pub optimize_rewrite: bool,
    pub optimize_remove_nop: bool,
    pub parser_threads: Option<usize>,
}

Parser optimization and lowering options.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

optimize_local_memory_allocation: bool

Whether to optimize local memory allocation by skipping allocation of unused local memories.

optimize_rewrite: bool

Whether to run the peephole rewrite optimizer.

optimize_remove_nop: bool

Whether to remove Nop and MergeBarrier instructions after rewriting.

parser_threads: Option<usize>

Number of threads to use for parallel parsing.

Requires the parallel feature. Ignored when the feature is disabled.

• None: auto-detect based on available parallelism
• Some(1): force single-threaded
• Some(n): use up to n workers

Implementations

impl ParserOptions

pub const fn with_local_memory_allocation_optimization( self, enabled: bool, ) -> Self

Enable or disable the optimization that skips allocating unused local memories.

pub const fn optimize_local_memory_allocation(&self) -> bool

Returns whether unused local memory allocation optimization is enabled.

pub const fn with_rewrite_optimization(self, enabled: bool) -> Self

Enable or disable the peephole rewrite optimizer.

pub const fn optimize_rewrite(&self) -> bool

Returns whether the peephole rewrite optimizer is enabled.

pub const fn with_nop_removal_optimization(self, enabled: bool) -> Self

Enable or disable Nop/MergeBarrier removal after rewriting.

pub const fn optimize_remove_nop(&self) -> bool

Returns whether Nop/MergeBarrier removal is enabled.

pub const fn with_parser_threads(self, threads: usize) -> Self

Set the number of threads for parallel parsing.

Requires the parallel feature to have any effect.

pub const fn parser_threads(&self) -> Option<usize>

Returns the configured parser thread count, or None for auto-detect.

Trait Implementations
