Struct ParamBind 

pub struct ParamBind<'a, V>
where
    V: SQLParam,
{
    pub name: &'a str,
    pub value: V,
}

A value to bind to the placeholder called name.

Pass these to SQL::bind or to a prepared statement. TypedPlaceholder::bind creates one with a type check.

Examples

use drizzle_core::{ParamBind, Placeholder, SQL, ToSQL};

let sql: SQL<'_, Value> = Placeholder::named("limit").to_sql();
let bound = sql.bind([ParamBind::new("limit", Value(20))]);
assert_eq!(bound.params().collect::<Vec<_>>(), [&Value(20)]);

Fields

name: &'a str

The placeholder name. Empty for a positional binding.

value: V

The value to bind.

Implementations

impl<'a, V> ParamBind<'a, V>

where V: SQLParam,

pub const fn new(name: &'a str, value: V) -> ParamBind<'a, V>

Creates a binding for the placeholder name.

pub const fn positional(value: V) -> ParamBind<'a, V>

Creates a binding with no name, matched by position.

Trait Implementations

impl<'a, V> Clone for ParamBind<'a, V>

where V: Clone + SQLParam,

fn clone(&self) -> ParamBind<'a, V>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a, V> Debug for ParamBind<'a, V>

where V: Debug + SQLParam,

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

Formats the value using the given formatter.
