Enum OperationCondition 

pub enum OperationCondition {
    OldContentHash(Vec<u8>),
    AnchorExists(String),
    PathExists(String),
    PathAbsent(String),
}

Operation precondition.

Variants

OldContentHash(Vec<u8>)

Old content hash must match before the operation applies.

AnchorExists(String)

Named anchor must exist.

PathExists(String)

Path must exist.

PathAbsent(String)

Path must be absent.

Trait Implementations

impl CanonicalEncode for OperationCondition

fn encode_canonical(&self, writer: &mut CanonicalWriter) -> Result<()>

Encode this value into canonical bytes.

fn to_canonical_bytes(&self) -> Result<Vec<u8>>

Return canonical bytes for this value.

impl Clone for OperationCondition

fn clone(&self) -> OperationCondition

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OperationCondition

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

Formats the value using the given formatter.

impl Eq for OperationCondition

impl Ord for OperationCondition

fn cmp(&self, other: &OperationCondition) -> 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 OperationCondition

fn eq(&self, other: &OperationCondition) -> 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 OperationCondition

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