Struct SessionId 

#[repr(transparent)]
pub struct SessionId(pub [u8; 16]);

Identifies one client session.

Session IDs are allocated by the server at session open (128 bits, drawn from a CSPRNG by the allocating service; this crate is dependency-frozen and deliberately does not mint them). The all-zero value is reserved.

Canonical text form: strict lowercase hexadecimal, 32 characters.

Tuple Fields

0: [u8; 16]

Implementations

impl SessionId

pub const ZERO: Self

The all-zero session identifier (reserved).

pub const fn from_bytes(bytes: [u8; 16]) -> Self

Wraps raw bytes without copying.

pub const fn as_bytes(&self) -> &[u8; 16]

Borrows the raw 16 bytes.

pub fn to_hex(self) -> String

Canonical text form: strict lowercase hexadecimal (32 chars).

Trait Implementations

impl Clone for SessionId

fn clone(&self) -> SessionId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SessionId

impl Debug for SessionId

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SessionId

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for SessionId

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

Formats the value using the given formatter.

impl Eq for SessionId

impl FromStr for SessionId

fn from_str(text: &str) -> Result<Self, Self::Err>

Parses the canonical 32-character hex form. Lenient by contract, like the mongreldb-types identifiers: hyphens are ignored at any position (so the hyphenated UUID form 8-4-4-4-12 parses) and uppercase hex digits are accepted.

type Err = SessionIdParseError

The associated error which can be returned from parsing.

impl Hash for SessionId

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 SessionId

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

fn eq(&self, other: &SessionId) -> bool

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for SessionId

fn partial_cmp(&self, other: &SessionId) -> 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 SessionId

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
