Struct codepage_437::Cp437Dialect

pub struct Cp437Dialect { /* fields omitted */ }

Specifier for the specific kind of cp437.

Dialects are instances of this type, aggregating data necessary to perform conversions.

Methods

impl Cp437Dialect

pub fn overlap_unicode(&self, unicode: char) -> bool

Check, whether the specified Unicode codepoint overlaps with a cp437 one.

pub fn overlap_cp437(&self, cp437: u8) -> bool

Check, whether the specified cp437 codepoint overlaps with a Unicode one.

pub fn decode(&self, cp437: u8) -> char

Decode a single cp437 codepoint into a Unicode one.

pub fn encode(&self, unicode: char) -> Option<u8>

Try to encode a single Unicode codepoint as a cp437 one.

pub fn remap(&mut self, cp437: u8, unicode: char) -> &mut Cp437Dialect

Map the specified cp437 codepoint mapped to the specified unicode character instead.

Examples

Remap √ to ✓:

let square_root_or_checkmark = CP437_WINGDINGS.encode('√').unwrap();

let mut mapping = CP437_WINGDINGS.clone();
mapping.remap(square_root_or_checkmark, '✓');
assert_eq!(mapping.decode(square_root_or_checkmark), '✓');
