Struct enso_flexer::group::Registry[−][src]

pub struct Registry { /* fields omitted */ }
Expand description

The group Registry is a container for Groups in the flexer implementation.

It allows groups to contain associations between themselves, and also implements useful conversions for groups.

Implementations

impl Registry[src]

pub fn define_group(
    &mut self,
    name: impl Into<String>,
    parent_index: Option<Identifier>
) -> Identifier[src]

Defines a new group of rules for the lexer with the specified name and parent.

It returns the identifier of the newly-created group.

pub fn add_group(&mut self, group: Group) -> Identifier[src]

Adds an existing group to the registry, updating and returning its identifier.

pub fn create_rule(
    &mut self,
    group: Identifier,
    pattern: &Pattern,
    callback: impl AsRef<str>
)[src]

Creates a rule that matches pattern for the group identified by group_id.

Panics if group_id refers to a nonexistent group.

pub fn add_rule(&mut self, group: Identifier, rule: Rule)[src]

Associates the provided rule with the group identified by group_id.

Panics if group_id refers to a nonexistent group.

pub fn rules_for(&self, group: Identifier) -> Vec<&Rule>ⓘ

Notable traits for Vec<u8, A>

impl<A> Write for Vec<u8, A> where
    A: Allocator, 
[src]

Collates the entire set of rules that are matchable when the lexer has the group identified by group_id as active.

This set of rules includes the rules inherited from any parent groups.

pub fn group(&self, group: Identifier) -> &Group[src]

Obtains a reference to the group for the given group_id.

As group identifiers can only be created by use of this Registry, this will always succeed.

pub fn group_mut(&mut self, group: Identifier) -> &mut Group[src]

Obtains a mutable reference to the group for the given group_id.

As group identifiers can only be created by use of this Registry, this will always succeed.

pub fn to_nfa_from(&self, group_id: Identifier) -> AutomatonData[src]

Converts the group identified by group_id into an NFA.

Returns None if the group does not exist, or if the conversion fails.

pub fn all(&self) -> &Vec<Group>ⓘ

Notable traits for Vec<u8, A>

impl<A> Write for Vec<u8, A> where
    A: Allocator, 
[src]

Get an immutable reference to the groups contained within the registry.
