Struct vhdl_lang::TokenId

pub struct TokenId(/* private fields */);

A TokenId represents a unique value that is used to access a token. A token ID cannot be created directly by the user. Instead, the value must be taken from the AST.

Implementations

impl TokenId

The TokenId represents an index into an array of tokens. As access is restricted (only the token stream creates and raw access to the vector of tokens is done using the parse context), a TokenId is always guaranteed to point to a valid token.

pub fn pos<'a>(&'a self, ctx: &'a dyn TokenAccess) -> &SrcPos

Trait Implementations

impl Clone for TokenId

fn clone(&self) -> TokenId

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TokenId

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

Formats the value using the given formatter.

impl From<TokenId> for TokenSpan

fn from(value: TokenId) -> Self

Converts to this type from the input type.

impl HasTokenSpan for TokenId

fn get_start_token(&self) -> TokenId

fn get_end_token(&self) -> TokenId

fn get_token_slice<'a>(&self, tokens: &'a dyn TokenAccess) -> &'a [Token]

fn get_pos(&self, tokens: &dyn TokenAccess) -> SrcPos

fn get_span(&self, ctx: &dyn TokenAccess) -> SrcPos

fn span(&self) -> TokenSpan

impl Ord for TokenId

fn cmp(&self, other: &TokenId) -> 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 TokenId

fn eq(&self, other: &TokenId) -> 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 TokenId

fn partial_cmp(&self, other: &TokenId) -> 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.
