Struct SolutionFailure

pub struct SolutionFailure<'a> {
    pub attempt_block_num: i64,
    pub attempt_block_addr: ContentAddress,
    pub attempt_solution_ix: u32,
    pub err_msg: Cow<'a, str>,
}

A failed attempt at applying a solution at a particular location within a particular block.

The builder stores these in order to provide solution submitters feedback in the case that a solution could not be applied trivially and did not make it into a block.

Fields

attempt_block_num: i64

The number of the block in which the builder attempted to apply the solution.

attempt_block_addr: ContentAddress

The address of the block in which the builder attempted to apply the solution.

attempt_solution_ix: u32

The solution index within the block at which the builder attempted to apply the solution.

err_msg: Cow<'a, str>

An error message describing why the builder failed to apply the solution.

Trait Implementations

impl<'a> Clone for SolutionFailure<'a>

fn clone(&self) -> SolutionFailure<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for SolutionFailure<'a>

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

Formats the value using the given formatter.

impl<'de, 'a> Deserialize<'de> for SolutionFailure<'a>

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'a> Hash for SolutionFailure<'a>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'a> Ord for SolutionFailure<'a>

fn cmp(&self, other: &SolutionFailure<'a>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<'a> PartialEq for SolutionFailure<'a>

fn eq(&self, other: &SolutionFailure<'a>) -> 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.

impl<'a> PartialOrd for SolutionFailure<'a>

fn partial_cmp(&self, other: &SolutionFailure<'a>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl<'a> Serialize for SolutionFailure<'a>

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
