Implementations

impl Sequence

pub fn native() -> Self

pub fn program( environment: &Environment, page: &CodePage, ) -> Result<Self, String>

The program’s sequence: its PROGRAM COLLATING SEQUENCE, else EBCDIC.

pub fn named( environment: &Environment, name: &str, page: &CodePage, ) -> Result<Self, String>

pub fn of(alphabet: &Alphabet, page: &CodePage) -> Result<Self, String>

STANDARD-1 and STANDARD-2 are 7-bit ASCII’s order: ASCII_COLLATION in numeric::assumptions.

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

A figurative constant’s character: HIGH-VALUE and LOW-VALUE are this sequence’s highest and lowest.

pub fn collation(&self) -> &Collation

pub fn is_native(&self) -> bool

pub fn positions(&self) -> [u8; 256]

Each character’s position, from 0: what a sort key collates by.

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

FUNCTION ORD: the character’s position, from 1.

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

FUNCTION CHAR: the character at a position, from 1; the first given it when several share it.

pub fn count(&self) -> usize

How many positions there are: the most FUNCTION CHAR takes.
