Struct SnapId 

pub struct SnapId(/* private fields */);

A unique identifier for a snap target.

Kept as a distinct type from UnitId so that the two cannot be accidentally mixed at call sites. Invariant: the wrapped value is always strictly positive.

Implementations

impl SnapId

pub fn new(raw: i64) -> Result<Self, IdError>

Construct a SnapId from a raw i64.

Errors

Condition	Error variant
raw == 0	IdError::ZeroId
raw < 0	IdError::NegativeId

pub fn get(self) -> i64

Return the underlying i64 value.

Trait Implementations

impl Clone for SnapId

fn clone(&self) -> SnapId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SnapId

impl Debug for SnapId

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

Formats the value using the given formatter.

impl Eq for SnapId

impl Hash for SnapId

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 Ord for SnapId

fn cmp(&self, other: &SnapId) -> 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 PartialEq for SnapId

fn eq(&self, other: &SnapId) -> 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 PartialOrd for SnapId

fn partial_cmp(&self, other: &SnapId) -> 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.
