Ct

Struct Ct 

Source
pub struct Ct;
Available on crate feature modmath only.
Expand description

Constant-time marker.

Selects constant-time implementations of operation primitives — bodies whose execution time and memory access pattern do not depend on operand values. Appropriate for code that handles secret values (signing, scalar multiplication on secret scalars, Montgomery multiplication on secret operands).

Calls to subtle::ConditionallySelectable, ConstantTimeEq, and related traits are only available for FixedUInt<_, _, Ct>` — wrong- variant calls become compile errors, not silent NCT execution.

Trait Implementations§

Source§

impl Clone for Ct

Source§

fn clone(&self) -> Ct

Returns a duplicate of the value. Read more
1.0.0 (const: unstable) · Source§

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

Performs copy-assignment from source. Read more
Source§

impl Debug for Ct

Source§

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

Formats the value using the given formatter. Read more
Source§

impl Default for Ct

Source§

fn default() -> Ct

Returns the “default value” for a type. Read more
Source§

impl PartialEq for Ct

Source§

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

Tests for self and other values to be equal, and is used by ==.
1.0.0 (const: unstable) · Source§

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

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