Crate sim_text 

Exact UTF-16 code-unit text with explicit scalar projections.

CodeUnitString preserves every u16, including lone surrogates and NUL. It deliberately carries no JavaScript, JVM, codec, or interning policy.

Structs

CodePointIter

Iterator over code-point chunks represented as exact code-unit strings.

CodeUnitOffset

An offset in the exact UTF-16 code-unit sequence.

CodeUnitRange

A half-open range in the exact UTF-16 code-unit sequence.

CodeUnitString

An exact sequence of UTF-16 code units.

CodeUnitStringReadConstructor

Standard read constructor for CodeUnitString.

CodeUnitStringShape

Shape that accepts exact-unit strings, never ordinary scalar strings.

InvalidSurrogate

Located evidence for the first invalid UTF-16 code unit.

ScalarOffset

An offset in the Unicode scalar sequence.

ScalarRange

A half-open range in the Unicode scalar sequence.

Enums

CodeUnitStringError

Failure to construct or project an exact code-unit string.

OffsetConversionError

Failure to convert between bounded offset domains.

Constants

CODE_UNIT_STRING_SYMBOL

Stable class/tag symbol used by the standard read-construct representation.

MAX_CODE_UNITS

The largest code-unit allocation representable by Rust’s collection APIs.

Functions

code_unit_string_browse

Browse table for an exact-unit string.

code_unit_string_from_expr

Recover exact code units from the tagged codec-neutral representation.

code_unit_string_to_expr

Project exact code units into the codec-neutral expression graph.

scalar_text

Convert for a scalar-text-only codec, refusing at the exact bad unit.
