u24

vest_lib::regular::uints

Struct u24 

Source 
pub struct u24(pub [u8; 3]);
Expand description

Vest’s u24 (3-byte unsigned integer) type. For simplicity, this type always stores the integer in big-endian byte order.

Tuple Fields§

§0: [u8; 3]

Implementations§

Source§

impl u24

Source

pub open spec fn spec_as_u32(&self) -> u32

{
    let s = self.0;
    let bytes = seq![0, s[0], s[1], s[2]];
    u32::spec_from_be_bytes(bytes)
}

Converts the u24 to a u32.

Source

pub exec fn as_u32(&self) -> o : u32

ensures
o == self.spec_as_u32(),

Converts the u24 to a u32.
