Enum ic_stable_structures::storable::Bound

pub enum Bound {
    Unbounded,
    Bounded {
        max_size: u32,
        is_fixed_size: bool,
    },
}

States whether the type’s size is bounded or unbounded.

Variants

Unbounded

The type has no size bounds.

Bounded

The type has size bounds.

Fields

max_size: u32

The maximum size, in bytes, of the type when serialized.

is_fixed_size: bool

True if all the values of this type have fixed-width encoding. Some data structures, such as stable vector, can take advantage of fixed size to avoid storing an explicit entry size.

Examples: little-/big-endian encoding of u16/u32/u64, tuples and arrays of fixed-size types.

Implementations

impl Bound

pub const fn max_size(&self) -> u32

Returns the maximum size of the type if bounded, panics if unbounded.

pub const fn is_fixed_size(&self) -> bool

Returns true if the type is fixed in size, false otherwise.

Trait Implementations

impl Debug for Bound

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

Formats the value using the given formatter.

impl PartialEq for Bound

fn eq(&self, other: &Bound) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
