Enum oem_cp::code_table_type::TableType

pub enum TableType {
    Complete(&'static [char; 128]),
    Incomplete(&'static [Option<char>; 128]),
}

Wrapper enumerate for decoding tables

It has 2 types: Complete, complete tables (it doesn’t have undefined codepoints) / Incomplete, incomplete tables (does have ones)

Variants

Complete(&'static [char; 128])

complete table, which doen’t have any undefined codepoints

Incomplete(&'static [Option<char>; 128])

incomplete table, which has some undefined codepoints

Implementations

impl TableType

pub fn decode_string_checked<'a, T: Into<Cow<'a, [u8]>>>( &self, src: T ) -> Option<String>

Wrapper function for decoding bytes encoded in SBCSs

This function returns None if any bytes bumps into undefined codepoints

Arguments

• src - bytes encoded in SBCS

Examples

use oem_cp::code_table::{DECODING_TABLE_CP437, DECODING_TABLE_CP874};
use oem_cp::code_table_type::TableType;
use TableType::{Complete,Incomplete};

assert_eq!(Complete(&DECODING_TABLE_CP437).decode_string_checked(vec![0xFB, 0xAC, 0x3D, 0xAB]), Some("√¼=½".to_string()));
// means shrimp in Thai (U+E49 => 0xE9)
assert_eq!(Incomplete(&DECODING_TABLE_CP874).decode_string_checked(vec![0xA1, 0xD8, 0xE9, 0xA7]), Some("กุ้ง".to_string()));
// 0xDB-0xDE,0xFC-0xFF is invalid in CP874 in Windows (strict mode)
assert_eq!(Incomplete(&DECODING_TABLE_CP874).decode_string_checked(vec![0x30, 0xDB]), None);

pub fn decode_string_lossy<'a, T: Into<Cow<'a, [u8]>>>(&self, src: T) -> String

Wrapper function for decoding bytes encoded in SBCSs

Undefined codepoints are replaced with U+FFFD.

Arguments

• src - bytes encoded in SBCS

Examples

use oem_cp::code_table::{DECODING_TABLE_CP437, DECODING_TABLE_CP874};
use oem_cp::code_table_type::TableType;
use TableType::{Complete,Incomplete};

assert_eq!(Complete(&DECODING_TABLE_CP437).decode_string_lossy(vec![0xFB, 0xAC, 0x3D, 0xAB]), "√¼=½".to_string());
// means shrimp in Thai (U+E49 => 0xE9)
assert_eq!(Incomplete(&DECODING_TABLE_CP874).decode_string_lossy(vec![0xA1, 0xD8, 0xE9, 0xA7]), "กุ้ง".to_string());
// 0xDB-0xDE,0xFC-0xFF is invalid in CP874 in Windows (strict mode)
assert_eq!(Incomplete(&DECODING_TABLE_CP874).decode_string_lossy(vec![0x30, 0xDB]), "0\u{FFFD}".to_string());
