Struct SeqKey 

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

A validated sequence key: non-empty, valid UTF-8 (guaranteed by String), and at most MAX_SEQ_KEY_LEN bytes. try_new is the single validation site — a value of this type is proof the key is in range.

The serde impls are hand-written (not derived) so deserialization routes through try_new: a derived Deserialize for a newtype builds the inner String directly and would be a second construction site that bypasses the invariant. Mirrors crate::peer::PeerEndpoint’s validate-on-deserialize discipline. Serialize emits the bare string (newtype-transparent), so the on-disk and wire byte layout is unchanged.

Implementations

impl SeqKey

pub fn try_new(s: impl Into<String>) -> Result<Self, CoreError>

pub fn as_str(&self) -> &str

Trait Implementations

impl Clone for SeqKey

fn clone(&self) -> SeqKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SeqKey

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SeqKey

Available on crate feature serde only.

fn deserialize<D: Deserializer<'de>>(deserializer: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl Eq for SeqKey

impl Hash for SeqKey

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 SeqKey

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

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

fn partial_cmp(&self, other: &SeqKey) -> 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 Serialize for SeqKey

Available on crate feature serde only.

fn serialize<S: Serializer>(&self, serializer: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.
