Implementations

impl Prefix

pub fn upper(self) -> &'static str

Returns the name in uppercase, such as “KILO”.

Examples

use number_prefix::Prefix;

assert_eq!("GIGA", Prefix::Giga.upper());
assert_eq!("GIBI", Prefix::Gibi.upper());

pub fn caps(self) -> &'static str

Returns the name with the first letter capitalised, such as “Mega”.

Examples

use number_prefix::Prefix;

assert_eq!("Giga", Prefix::Giga.caps());
assert_eq!("Gibi", Prefix::Gibi.caps());

pub fn lower(self) -> &'static str

Returns the name in lowercase, such as “giga”.

Examples

use number_prefix::Prefix;

assert_eq!("giga", Prefix::Giga.lower());
assert_eq!("gibi", Prefix::Gibi.lower());

pub fn symbol(self) -> &'static str

Returns the short-hand symbol, such as “T” (for “tera”).

Examples

use number_prefix::Prefix;

assert_eq!("G",  Prefix::Giga.symbol());
assert_eq!("Gi", Prefix::Gibi.symbol());
