Enum parol::grammar::attributes::SymbolAttribute

pub enum SymbolAttribute {
    None,
    RepetitionAnchor,
    Option,
    Clipped,
}

Attributes applicable to a grammar symbol

Variants

None

No valid attribute, default value

RepetitionAnchor

The symbol is actually a collection, i.e. a vector Is attached to a non-terminal symbol. If an argument with this attribute appears in the argument list of a semantic action this collection should be reversed.

Option

The symbol is an option with the inner type that is determined by the non-terminal

Clipped

The symbol is not relevant for the AST and should not be propagated.

Trait Implementations

impl Clone for SymbolAttribute

fn clone(&self) -> SymbolAttribute

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SymbolAttribute

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

Formats the value using the given formatter.

impl<T, W> Decorate<T, W> for SymbolAttribute

where T: Display, W: Write,

fn decorate(&self, out: &mut W, decoratee: &T) -> Result<(), Error>

Function used for decorated formatting

impl Default for SymbolAttribute

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for SymbolAttribute

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for SymbolAttribute

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

Formats the value using the given formatter.

impl Hash for SymbolAttribute

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for SymbolAttribute

fn cmp(&self, other: &SymbolAttribute) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for SymbolAttribute

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for SymbolAttribute

fn partial_cmp(&self, other: &SymbolAttribute) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for SymbolAttribute

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TS for SymbolAttribute

type WithoutGenerics = SymbolAttribute

If this type does not have generic parameters, then WithoutGenerics should just be Self. If the type does have generic parameters, then all generic parameters must be replaced with a dummy type, e.g ts_rs::Dummy or (). The only requirement for these dummy types is that EXPORT_TO must be None.

fn ident() -> String

Identifier of this type, excluding generic parameters.

const DOCS: Option<&'static str> = _

JSDoc comment to describe this type in TypeScript - when TS is derived, docs are automatically read from your doc comments or #[doc = ".."] attributes

fn name() -> String

Name of this type in TypeScript, including generic parameters

fn decl_concrete() -> String

Declaration of this type using the supplied generic arguments. The resulting TypeScript definition will not be generic. For that, see TS::decl(). If this type is not generic, then this function is equivalent to TS::decl().

fn decl() -> String

Declaration of this type, e.g. type User = { user_id: number, ... }. This function will panic if the type has no declaration.

fn inline() -> String

Formats this types definition in TypeScript, e.g { user_id: number }. This function will panic if the type cannot be inlined.

fn inline_flattened() -> String

Flatten an type declaration.
This function will panic if the type cannot be flattened.

fn generics() -> impl TypeList

where Self: 'static,

Returns a TypeList containing all generic parameters of this type. If this type is not generic, this will return an empty TypeList.

fn output_path() -> Option<&'static Path>

Returns the output path to where T should be exported.
The returned path does not include the base directory from TS_RS_EXPORT_DIR.

fn dependency_types() -> impl TypeList

where Self: 'static,

Returns a TypeList of all types on which this type depends.

fn dependencies() -> Vec<Dependency>

where Self: 'static,

Resolves all dependencies of this type recursively.

fn export() -> Result<(), ExportError>

where Self: 'static,

Manually export this type to the filesystem. To export this type together with all of its dependencies, use TS::export_all.

fn export_all() -> Result<(), ExportError>

where Self: 'static,

Manually export this type to the filesystem, together with all of its dependencies.
To export only this type, without its dependencies, use TS::export.

fn export_all_to(out_dir: impl AsRef<Path>) -> Result<(), ExportError>

where Self: 'static,

Manually export this type into the given directory, together with all of its dependencies.
To export only this type, without its dependencies, use TS::export.

fn export_to_string() -> Result<String, ExportError>

where Self: 'static,

Manually generate bindings for this type, returning a String.
This function does not format the output, even if the format feature is enabled. TODO

fn default_output_path() -> Option<PathBuf>

Returns the output path to where T should be exported.
