Struct Alpha2 

pub struct Alpha2(/* 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-2 string.

Implementations

impl Alpha2

pub const fn from_alpha2(s: &str) -> Result<Self, Error>

Create a new value from an Alpha2 string.

Errors

• Error::InvalidLength if the given slice is not 2 characters.
• Error::InvalidCharset if the given slice does not contain ASCII characters.
• Error::UnknownString if the given slice does not match any known Alpha2 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_alpha3(value: Alpha3) -> Self

Create a new value from an Alpha3 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.
