TString
struct TString[origins: ImmOrigin, array_origin: ImmOrigin]
A template string that captures interpolated values at compile-time.
TString is a zero-cost abstraction for string interpolation that preserves type information and defers formatting until explicitly requested. Unlike regular strings or f-strings, TString retains the original format template and typed values, enabling efficient lazy formatting and type-safe string composition.
TString instances are created by the compiler when using t-string literal
syntax: t"Hello {name}!".
Parameters
- origins (
ImmOrigin): The union of the origins of the interpolated values. - array_origin (
ImmOrigin): The origin of the array holding those values, which the t-string expression owns and thisTStringborrows.

Methods
write_to
def write_to(self, mut writer: T)
Write the formatted string to a writer.
This method implements the Writable trait by formatting the TString's
template with its interpolated values and writing the result to the
provided writer.
Args:
- writer (
T): The writer to output the formatted string to.
write_repr_to
def write_repr_to(self, mut writer: T)
Write a debug representation of the TString to a writer.
The interpolated values are type-erased, so neither their types nor
their values are recoverable here; use write_to to render them.
Args:
- writer (
T): The writer to output the debug representation to.
