Struct AsciiTable

Source

pub struct AsciiTable { /* private fields */ }

Expand description

Represents a table of ASCII characters.

The table is implemented as a HashMap of Byte values to AsciiChar

It maps the valid ASCII Byte values to their corresponding AsciiChar values.

§Examples

use brainfoamkit_lib::{
    AsciiTable,
    Byte,
};

let ascii_table = AsciiTable::new();

assert_eq!(
    ascii_table.get(Byte::from(0)).unwrap().character_code(),
    "CNUL"
);
assert_eq!(
    ascii_table.get(Byte::from(1)).unwrap().character_code(),
    "CSOH"
);
assert_eq!(
    ascii_table.get(Byte::from(2)).unwrap().character_code(),
    "CSTX"
);

impl AsciiTable

Source

pub fn new() -> Self

Create a new AsciiTable instance.

This will create a new AsciiTable instance with all the valid ASCII characters pre-populated.

§Examples

use brainfoamkit_lib::{
    AsciiTable,
    Byte,
};

let ascii_table = AsciiTable::new();

assert_eq!(
    ascii_table.get(Byte::from(0)).unwrap().character_code(),
    "CNUL"
);

Source

pub fn get(&self, byte: Byte) -> Option<&AsciiChar>

Get an ASCII character from the table by its byte value.

§Arguments

byte - The Byte value of the ASCII character to get.

§Returns

Some(&AsciiChar) - The AsciiChar value corresponding to the given Byte value.
None - If the given Byte value does not correspond to an ASCII character.

§Examples

use brainfoamkit_lib::{
    AsciiTable,
    Byte,
};

let ascii_table = AsciiTable::new();

assert_eq!(
    ascii_table.get(Byte::from(0)).unwrap().character_code(),
    "CNUL"
);
assert_eq!(
    ascii_table.get(Byte::from(1)).unwrap().character_code(),
    "CSOH"
);
assert_eq!(
    ascii_table.get(Byte::from(2)).unwrap().character_code(),
    "CSTX"
);
