Struct Threshold 

pub struct Threshold {
    pub threshold: usize,
    pub subconditions: Vec<Condition>,
}

N-of-M threshold condition.

Satisfied when at least threshold of the subconditions verify successfully. Subconditions can be any Condition variant, including nested thresholds.

Fields

threshold: usize

Minimum number of valid subconditions required.

subconditions: Vec<Condition>

Subconditions to evaluate.

Implementations

impl Threshold

pub fn verify(&self) -> Result<(), Error>

Verifies that at least threshold subconditions are satisfied.

Returns Ok(()) if the threshold is met, or Err with details about how many conditions passed versus required.

A threshold of zero is always satisfied, regardless of subconditions.

Trait Implementations

impl<'__de, __Context> BorrowDecode<'__de, __Context> for Threshold

fn borrow_decode<__D: BorrowDecoder<'__de, Context = __Context>>( decoder: &mut __D, ) -> Result<Self, DecodeError>

Attempt to decode this type with the given BorrowDecode.

impl Clone for Threshold

fn clone(&self) -> Threshold

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Threshold

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

Formats the value using the given formatter.

impl<__Context> Decode<__Context> for Threshold

fn decode<__D: Decoder<Context = __Context>>( decoder: &mut __D, ) -> Result<Self, DecodeError>

Attempt to decode this type with the given Decode.

impl Encode for Threshold

fn encode<__E: Encoder>(&self, encoder: &mut __E) -> Result<(), EncodeError>

Encode a given type.

impl PartialEq for Threshold

fn eq(&self, other: &Threshold) -> 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.
