Struct UniqueId

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

A UniqueId that can be used within a database. Is not cryptographically secure and could be bruteforced.

Contains 10bytes

• 0..5 are seconds since the UNIX_EPOCH
• 5..10 are random

Implementations

impl UniqueId

pub fn new() -> UniqueId

pub const fn from_raw(inner: [u8; 10]) -> UniqueId

This creates a unique id with it’s raw content making it able to be called in a const context.

pub fn from_slice_unchecked(slice: &[u8]) -> UniqueId

pub fn to_b64(&self) -> String

pub fn parse_from_b64<T>(b64: T) -> Result<UniqueId, DecodeError>

where T: AsRef<[u8]>,

If the string is not 14 bytes long returns InvalidLength

pub fn from_bytes(bytes: [u8; 10]) -> UniqueId

pub fn into_bytes(self) -> [u8; 10]

pub fn since_unix_secs(&self) -> u64

pub fn as_slice(&self) -> &[u8]

Trait Implementations

impl Clone for UniqueId

fn clone(&self) -> UniqueId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for UniqueId

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

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for UniqueId

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

Formats the value using the given formatter.

impl<'r> FromSql<'r> for UniqueId

fn from_sql( ty: &Type, raw: &'r [u8], ) -> Result<UniqueId, Box<dyn Error + Send + Sync>>

Creates a new value of this type from a buffer of data of the specified Postgres Type in its binary format.

fn accepts(ty: &Type) -> bool

Determines if a value of this type can be created from the specified Postgres Type.

fn from_sql_null(ty: &Type) -> Result<Self, Box<dyn Error + Send + Sync>>

Creates a new value of this type from a NULL SQL value.

fn from_sql_nullable( ty: &Type, raw: Option<&'a [u8]>, ) -> Result<Self, Box<dyn Error + Send + Sync>>

A convenience function that delegates to from_sql and from_sql_null depending on the value of raw.

impl FromStr for UniqueId

type Err = DecodeError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<UniqueId, <UniqueId as FromStr>::Err>

Parses a string s to return a value of this type.

impl Hash for UniqueId

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

where __H: Hasher,

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 ParamData for UniqueId

fn is_null(&self) -> bool

impl PartialEq for UniqueId

fn eq(&self, other: &UniqueId) -> 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.

where S: Serializer,

Serialize this value into the given Serde serializer.

where UniqueId: Sized,

Converts the value of self into the binary format of the specified Postgres Type, appending it to out.

fn accepts(ty: &Type) -> bool

where UniqueId: Sized,

Determines if a value of this type can be converted to the specified Postgres Type.

fn to_sql_checked( &self, ty: &Type, out: &mut BytesMut, ) -> Result<IsNull, Box<dyn Error + Send + Sync>>

An adaptor method used internally by Rust-Postgres.

fn encode_format(&self, _ty: &Type) -> Format

Specify the encode format
