Parsing context

Implementations

impl ParseContext

pub fn new() -> ParseContext

Create a new parsing context from this options object

pub fn new_with_comments() -> Self

Create a new parsing context from this options object, with comment parsing enabled

pub fn new_with_policy(policy: impl TypeTablePolicy + 'static) -> Self

Create a new parsing context from this options object, with a custom type table policy

pub fn new_with_comments_and_policy( policy: impl TypeTablePolicy + 'static, ) -> Self

Create a new parsing context from this options object, with a custom type table policy and comment parsing enabled

pub fn new_with_context(context: ParseContextData) -> Self

Create a new parsing context from this options object and pre-existing context data

pub fn clone_inner(&self) -> Self

Clone the parsing data and return the cloned context

pub fn into_data(self) -> Option<ParseContextData>

Consume this ParseContext and return its data. Will fail if there are multiple references to this context’s data.

pub fn data(&self) -> Ref<'_, ParseContextData>

Obtain a reference to the context’s data

pub fn data_mut(&self) -> RefMut<'_, ParseContextData>

Obtain an exclusive reference to the context’s data

pub fn with_policy( &self, policy: impl TypeTablePolicy + 'static, ) -> ParseContext

Create a new parse context cloning the given one’s data, but applies the given policy

impl ParseContext

pub fn is_type_name(&self, name: &str) -> bool

Return true if the given name is a type name

pub fn add_type_name(&self, name: Identifier) -> TypeName

Register name as a new type name

pub fn push_scope(&self)

Enter a new nesting level for declarations

pub fn pop_scope(&self)

Leave the current nesting level

pub fn new_identifier(&self, name: &Identifier, ctx: IdentifierContext)

Update the context data with a new identifier in a given context

impl ParseContext

pub fn has_comments(&self) -> bool

Return true if this parsing context supports comments

pub fn add_comment(&self, comment: Comment)

Add a new comment to the parsed comments list

Trait Implementations

impl Clone for ParseContext

fn clone(&self) -> ParseContext

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParseContext

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

Formats the value using the given formatter.

impl Default for ParseContext

fn default() -> ParseContext

Returns the “default value” for a type.

impl From<ParseContextData> for ParseContext

fn from(data: ParseContextData) -> Self

Converts to this type from the input type.

impl PartialEq for ParseContext

fn eq(&self, other: &ParseContext) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
