Struct StrGraphQLTokenSourceConfig 

pub struct StrGraphQLTokenSourceConfig {
    pub retain_comments: bool,
    pub retain_commas: bool,
    pub retain_whitespace: bool,
}

Configuration for StrGraphQLTokenSource controlling which trivia types are captured during lexing.

All flags default to true, meaning the lexer operates in full-fidelity mode by default — every comment, comma, and whitespace run is preserved as trivia on the emitted tokens. Set individual flags to false to discard specific trivia types for leaner output.

Example

use libgraphql_parser::token::StrGraphQLTokenSourceConfig;

// Full-fidelity (default): all trivia preserved
let full = StrGraphQLTokenSourceConfig::default();
assert!(full.retain_comments);
assert!(full.retain_commas);
assert!(full.retain_whitespace);

// Lean mode: discard all trivia
let lean = StrGraphQLTokenSourceConfig::no_trivia();
assert!(!lean.retain_comments);
assert!(!lean.retain_commas);
assert!(!lean.retain_whitespace);

Fields

retain_comments: bool

Whether to preserve # comments as GraphQLTriviaToken::Comment on emitted tokens.

When false, comments are still consumed (skipped) by the lexer but not recorded as trivia.

retain_commas: bool

Whether to preserve commas as GraphQLTriviaToken::Comma on emitted tokens.

When false, commas are still consumed (skipped) by the lexer but not recorded as trivia.

retain_whitespace: bool

Whether to preserve whitespace runs as GraphQLTriviaToken::Whitespace on emitted tokens.

When false, whitespace is still consumed (skipped) by the lexer but not recorded as trivia. This is the most impactful flag for performance since whitespace runs are frequent.

Implementations

impl StrGraphQLTokenSourceConfig

pub fn no_trivia() -> Self

Returns a config that discards all trivia (comments, commas, whitespace). Useful when only semantic tokens are needed and source reconstruction is not required.

Trait Implementations

impl Clone for StrGraphQLTokenSourceConfig

fn clone(&self) -> StrGraphQLTokenSourceConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StrGraphQLTokenSourceConfig

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

Formats the value using the given formatter.

impl Default for StrGraphQLTokenSourceConfig

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for StrGraphQLTokenSourceConfig

fn eq(&self, other: &StrGraphQLTokenSourceConfig) -> 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.
