Struct PostId 

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

Unique identifier for a post.

Implementations

impl PostId

pub fn new() -> Self

Create a new random ID.

pub fn as_uuid(&self) -> &Uuid

Get the inner UUID reference.

Trait Implementations

impl Clone for PostId

fn clone(&self) -> PostId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for PostId

impl Debug for PostId

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

Formats the value using the given formatter.

impl Default for PostId

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for PostId

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for PostId

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

Formats the value using the given formatter.

impl Eq for PostId

impl From<PostId> for Uuid

fn from(id: PostId) -> Self

Converts to this type from the input type.

impl From<PostId> for ModerationTargetId

Anything that can be moderated narrows to a ModerationTargetId.

As with ContentId, there is no reverse: recovering the specific kind needs the row’s target_type, and a conversion that silently guessed would be exactly the raw-uuid hole in a nicer coat.

fn from(id: PostId) -> Self

Converts to this type from the input type.

impl From<PostId> for ContentId

A ContentId can be produced from anything already known to be content — narrowing to “an id” from “an id we resolved” is always sound. The reverse needs a database lookup and is resolve_content_id’s job, which is why there is no From for it.

fn from(id: PostId) -> Self

Converts to this type from the input type.

impl From<PostId> for PostOrCommentId

fn from(id: PostId) -> Self

Converts to this type from the input type.

impl From<Uuid> for PostId

fn from(uuid: Uuid) -> Self

Converts to this type from the input type.

impl FromStr for PostId

Every id round-trips through its own Display.

Without this, anything that parses an id from a string — clap value_parsers, query strings, config files — has to widen the field back to a bare Uuid at the boundary and convert by hand, which is the exact laundering the newtype exists to prevent. agora-cli carried a hand-written parse_moderation_action_id for precisely this reason.

type Err = Error

The associated error which can be returned from parsing.

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

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

impl Hash for PostId

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 PostId

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

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for PostId

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
