Enum SizeFlag 

pub enum SizeFlag {
    Any,
    Exact(u32),
    Range(u32, u32),
}

Flags representing size constraints on attribute values.

Variants

Any

No constraint (default).

Exact(u32)

Value must be exactly N bytes.

Range(u32, u32)

Value must be between N and M bytes (inclusive).

Implementations

impl SizeFlag

pub fn is_constrained(&self) -> bool

Trait Implementations

impl Clone for SizeFlag

fn clone(&self) -> SizeFlag

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SizeFlag

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

Formats the value using the given formatter.

impl Default for SizeFlag

fn default() -> SizeFlag

Returns the “default value” for a type.

impl PartialEq for SizeFlag

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

Tests for self and other values to be equal, and is used by ==.

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

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