Struct RegexSetOptions 

pub struct RegexSetOptions { /* private fields */ }

Configuration for a RegexSet

Implementations

impl RegexSetOptions

pub fn new() -> Self

Create a new RegexSet options value with default settings.

pub fn delegate_size_limit(self, limit: usize) -> Self

Set the approximate size limit of each delegated sub-regex.

This option is forwarded from the wrapped regex crate. Note that depending on the used regex features there may be multiple delegated sub-regexes fed to the regex crate. As such the actual limit is closer to <number of delegated regexes> * delegate_size_limit.

pub fn delegate_dfa_size_limit(self, limit: usize) -> Self

Set the approximate size of the cache used by delegated DFAs.

This option is forwarded from the wrapped regex crate. Note that depending on the used regex features there may be multiple delegated sub-regexes fed to the regex crate. As such the actual limit is closer to <number of delegated regexes> * delegate_dfa_size_limit.

pub fn meta_nfa_size_limit(self, limit: Option<usize>) -> Self

Set the approximate NFA size limit for the regex-automata meta regex used to find the earliest match position.

Passing None disables the limit. The default is 64 MiB.

pub fn meta_hybrid_cache_capacity(self, limit: usize) -> Self

Set the cache capacity, in bytes, for the lazy DFA used by the regex-automata meta regex that finds the earliest match position.

The default is 64 MiB.

pub fn overlapping_dfa_cache_capacity(self, limit: usize) -> Self

Set the cache capacity, in bytes, for the lazy DFA used to find overlapping matches at a candidate match position.

The default is 64 MiB.

pub fn overlapping_dfa_skip_cache_capacity_check(self, yes: bool) -> Self

Configure whether the overlapping DFA builder should skip its minimum cache capacity check.

Enabling this can allow large DFAs to build when the default cache capacity check would reject them, but it may allocate more memory at build time. The default is true.

Trait Implementations

impl Default for RegexSetOptions

fn default() -> Self

Returns the “default value” for a type.
