GrammarFormatProfile

meta_language::grammar::fidelity

Struct GrammarFormatProfile 

Source 
pub struct GrammarFormatProfile { /* private fields */ }
Expand description

Capability profile for one grammar notation.

The embedded LanguageProfile carries the support-or-fallback invariant used by the document fidelity matrix. equivalent_constructs marks supported constructs whose round trip is semantically equivalent but not byte/canonical-form lossless.

Implementations§

Source§

impl GrammarFormatProfile

Source

pub const fn new(format: &'static str, profile: LanguageProfile) -> Self

Source

pub const fn language_profile(&self) -> &LanguageProfile

Source

pub const fn fallbacks(&self) -> &BTreeMap<String, String>

Source

pub const fn equivalent_constructs(&self) -> &BTreeSet<String>

Source

pub fn supports_construct(&self, construct: &str) -> bool

Source

pub fn construct_fallback(&self, construct: &str) -> Option<&str>

Documented lossy fallback for a construct this format cannot represent natively.

Source

pub fn construct_fidelity( &self, construct: &str, ) -> Option<GrammarFidelityLevel>

Fidelity level for a construct, or None when the construct is outside this profile’s vocabulary.
