Struct Alpha3 

pub struct Alpha3(/* private fields */);

A wrapper around the numeric enumeration requiring strings be Alpha-2 format.

When the serde feature is enabled, this type will be serialized as the Alpha-3 string.

Examples

use iso3166_static::Alpha3;
const ALPHA3_USA: &str = "USA";

let alpha3 = Alpha3::from_alpha3(ALPHA3_USA).expect("valid alpha3");

assert_eq!(ALPHA3_USA, alpha3.as_str());

Implementations

impl Alpha3

pub const fn from_alpha3(s: &str) -> Result<Self, Error>

Create a new value from an Alpha2 string.

This method strictly validates the given slice and only accepts valid upper-case Alpha3 codes with no padding.

Errors

• Error::InvalidLength if the given slice is not 3 characters.
• Error::InvalidCharset if the given slice contains non-ASCII-7 characters.
• Error::UnknownString if the given slice does not match any known Alpha3 code.

pub const fn from_u16(value: u16) -> Result<Self, Error>

Create a new value from an unsigned integer.

Errors

• Error::UnknownCode if the given code value is not a numeric code.

pub const fn from_alpha2(value: Alpha2) -> Self

Create a new value from an Alpha2 code.

pub const fn from_numeric(value: Numeric) -> Self

Create a new value from a numeric code.

pub const fn as_str(&self) -> &'static str

Retrieve the static Alpha2 code string for this value.
