Struct TokenTerm 

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

Canonical term text. Valid UTF-16 is stored as a string; unpaired units remain exact.

Serialization uses a JSON string for scalar text or an explicit {"utf16":[...]} object for unpaired units. Scalar and raw-unit construction give identical identity for the same valid text.

use uqa_analysis::TokenTerm;
let term = TokenTerm::from_utf16(vec![0xd83d]);
assert!(term.as_str().is_none());
assert_eq!(term.utf16().as_ref(), [0xd83d]);
assert!(term.into_string().is_err());

Implementations

impl TokenTerm

pub fn clone_budgeted( &self, budget: &MemoryBudget, poll: impl FnMut() -> AnalysisResult<()>, ) -> AnalysisResult<Budgeted<Self>>

Copy this term into independently reserved storage without changing scalar or raw-unit identity.

pub fn from_utf16_budgeted( input: Budgeted<Vec<u16>>, poll: impl FnMut() -> AnalysisResult<()>, ) -> AnalysisResult<Budgeted<Self>>

Consume reserved UTF-16 units, preserving isolated surrogates without replacement.

Valid input reserves the exact UTF-8 buffer before decoding and releases the UTF-16 lease only after freeing its buffer. The input must carry the reservation for its capacity. Cancellation is checked during both validation and conversion.

impl TokenTerm

pub fn from_utf16(units: Vec<u16>) -> Self

pub fn as_str(&self) -> Option<&str>

pub fn utf16(&self) -> Cow<'_, [u16]>

pub fn into_utf16(self) -> Vec<u16>

pub fn into_string(self) -> AnalysisResult<String>

Project to a Unicode string, returning an error instead of replacing unpaired units.

pub fn character_count(&self) -> usize

Count each scalar or isolated surrogate as one character.

pub fn utf16_len(&self) -> usize
