Struct PkSet 

pub struct PkSet { /* private fields */ }

Selected primary keys, each typed from the model’s PK field, so a key can never be bound against a PK column of another type (#1817).

Implementations

impl PkSet

pub const MAX_KEYS: usize = 10_000

Most keys one set holds: one IN list stays under every backend’s bind cap (SQLite: 32766).

pub fn parse<S: AsRef<str>>( model: &'static ModelSchema, raw: impl IntoIterator<Item = S>, ) -> Result<Self, BulkActionError>

Parse raw keys (form or URL values) with the PK field’s type.

Errors

BulkActionError::InvalidPk when the model has no PK, a key does not parse as its type, or past Self::MAX_KEYS keys.

pub fn new<V: Into<SqlValue>>( model: &'static ModelSchema, keys: impl IntoIterator<Item = V>, ) -> Result<Self, BulkActionError>

Typed keys. Integers are narrowed to the PK’s width; any other type mismatch is refused.

Errors

BulkActionError::InvalidPk when the model has no PK, a key does not fit its type, or past Self::MAX_KEYS keys.

pub fn model(&self) -> &'static ModelSchema

The model the keys belong to.

pub fn keys(&self) -> &[SqlValue]

The typed keys.

pub fn is_empty(&self) -> bool

true when no key is selected.

Trait Implementations

impl Clone for PkSet

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PkSet

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

Formats the value using the given formatter.
