Struct Options 

#[non_exhaustive]
pub struct Options {
    pub cache_capacity: usize,
}

Options of compile and compile_mut: Options::default().cache_capacity(8).

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.

cache_capacity: usize

The most traced signatures a compiled function keeps (least recently used first out); 0 never caches. Default 64.

Implementations

impl Options

pub fn cache_capacity(self, n: usize) -> Self

Sets the cache capacity.

pub fn compile<'f, I, O, F, R>(self, f: F) -> impl Fn(&I) -> Result<O> + 'f

where I: Tree, O: Tree, F: Fn(&I) -> R + 'f, R: IntoResult<Ok = O>,

compile with these options.

pub fn compile_mut<'f, S, I, O, F, R>( self, f: F, ) -> impl Fn(&mut S, &I) -> Result<O> + 'f

where S: Tree, I: Tree, O: Tree, F: Fn(&mut S, &I) -> R + 'f, R: IntoResult<Ok = O>,

compile_mut with these options.

Trait Implementations

impl Clone for Options

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Options

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

Formats the value using the given formatter.

impl Default for Options

fn default() -> Self

Returns the “default value” for a type.
