Enum Padding

pub enum Padding {
    Left {
        target_size: usize,
    },
    Right {
        target_size: usize,
    },
}

Provides information about padding expected when laying values in memory. Padding depends on the type of the value, but also on the embedding of the value in aggregates. E.g., in an array of u8, each u8 is “padded” to its size of one byte while as a struct field, it will be right padded to 8 bytes.

Implementations

impl Padding

pub fn default_for_u8(_value: u8) -> Self

Returns the default Padding for u8.

pub fn default_for_u64(_value: u64) -> Self

Returns the default Padding for u64.

pub fn default_for_byte_array(value: &[u8]) -> Self

Returns the default Padding for a byte array.

pub fn default_for_aggregate(aggregate_size: usize) -> Self

Returns the default Padding for an aggregate. aggregate_size is the overall size of the aggregate in bytes.

pub fn target_size(&self) -> usize

The target size in bytes.

Trait Implementations

impl Clone for Padding

fn clone(&self) -> Padding

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Padding

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Serialize for Padding

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
