Struct Reservation 

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

A request for SQLite to allocate a blob of a certain size.

When a Reservation is used as a prepared statement parameter, SQLite will create a BLOB of the requested length and set every byte in the blob to \0.

Implementations

impl Reservation

pub const fn new(bytes: isize) -> Self

Create a Reservation.

pub const fn len(&self) -> usize

The number of bytes to reserve, as a usize.

pub const fn into_inner(self) -> isize

The number of bytes to reserve, as an isize.

Trait Implementations

impl<'b> Bind<'b> for Reservation

type Value = Reservation

A type directly handled by the SQLite parameter binding API.

fn into_bind_value(self) -> Result<Self::Value>

Convert self into a directly bindable type.

impl<'b> Bind<'b> for Reservation

Binds a blob reservation via sqlite3_bind_zeroblob64.

When a Reservation is used as a prepared statement parameter, SQLite will create a BLOB of the requested length and set every byte in the blob to \0.

unsafe fn bind_parameter<'c>( self, statement: &Statement<'c>, index: BindIndex, ) -> Result<()>

where 'c: 'b,

Bind self as a SQLite prepared statement parameter.

unsafe fn bind_return<'c>(self, context: &ContextRef<'c>)

where 'b: 'c,

Available on crate feature functions only.

Bind self as the return value of a SQLite function.

impl Clone for Reservation

fn clone(&self) -> Reservation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Reservation

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

Formats the value using the given formatter.

impl<T> From<T> for Reservation

where isize: From<T>,

fn from(value: T) -> Self

Converts to this type from the input type.

impl Ord for Reservation

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

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

fn partial_cmp(&self, other: &Reservation) -> 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.
