What these semantics read of the running program beyond a Loc: its options, code page and collating sequence, its edited PICTUREs, and its items by the index a Loc carries.

Required Methods

fn options(&self) -> Options

fn page(&self) -> &'static CodePage

fn figurative(&self, f: Figurative) -> u8

A figurative constant’s character: HIGH-VALUE and LOW-VALUE are the collating sequence’s.

fn collation(&self) -> &Collation

fn ordinal(&self, byte: u8) -> u16

A character’s ordinal position in the collating sequence, from 1, which FUNCTION ORD gives.

fn character(&self, ordinal: i64) -> Option<u8>

The character at an ordinal position, which FUNCTION CHAR gives.

fn characters(&self) -> usize

How many characters the collating sequence orders.

fn decimal_point(&self) -> char

fn edit(&self, edit: u32) -> (&[Sym], &str)

An edited PICTURE’s symbols, and the currency sign it shows.

fn scaling(&self, item: usize) -> u32

PICTURE P positions to the right of an item’s digits.

fn item_name(&self, item: usize) -> String

The item a TRUNC(OPT) report names.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
