Struct Shape 

pub struct Shape {
    pub bytes: usize,
    pub heap: usize,
    pub nodes: usize,
    pub depth: usize,
}

Worst-case bounds for one finite value.

Fields

bytes: usize

Maximum canonical Postcard payload bytes.

heap: usize

Maximum requested heap bytes owned by the decoded value.

nodes: usize

Maximum visited value nodes, including zero-byte values.

depth: usize

Maximum nested value depth.

Implementations

impl Shape

pub const fn scalar(bytes: usize) -> Self

A leaf with no allocation.

pub const fn record(children: &[Self]) -> Self

A record with these children. Overflow saturates and fails admission.

pub const fn choice(tag_bytes: usize, alternatives: &[Self]) -> Self

A tagged choice, using the largest bound in each dimension.

Trait Implementations

impl Clone for Shape

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Shape

impl Debug for Shape

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

Formats the value using the given formatter.
