Struct Sqlite 

pub struct Sqlite;

SQLite dialect (? placeholders, LIMIT -1 before bare OFFSET).

Trait Implementations

impl Clone for Sqlite

fn clone(&self) -> Sqlite

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Sqlite

impl Debug for Sqlite

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

Formats the value using the given formatter.

impl Default for Sqlite

fn default() -> Sqlite

Returns the “default value” for a type.

impl Dialect for Sqlite

fn capabilities(&self) -> BackendCapabilities

Declared capabilities; the compiler rejects plans that exceed them.

fn write_placeholder(&self, out: &mut String, _index: usize)

Write the placeholder for the index-th (1-based) bind parameter.

fn cast_type(&self, ty: SqlType) -> &'static str

Type name used in CAST(.. AS <name>).

fn offset_requires_limit(&self) -> bool

Whether OFFSET requires a preceding LIMIT.

fn write_ident(&self, out: &mut String, ident: &str)

Write a quoted identifier. Embedded quote characters are doubled.

fn unbounded_limit(&self) -> &'static str

The LIMIT written before a bare OFFSET when offset_requires_limit is set.

fn like_escape_literal(&self) -> &'static str

The SQL string literal used as the LIKE .. ESCAPE character (one backslash).

fn default_values_sql(&self) -> &'static str

The tail of an INSERT INTO t that stores one row of defaults.

fn supports_aggregate_filter(&self) -> bool

Whether aggregates accept FILTER (WHERE ..). When not, the compiler rewrites AGG(x) FILTER (WHERE f) as AGG(CASE WHEN f THEN x END).

fn evaluates_assignments_in_order(&self) -> bool

Whether UPDATE .. SET a = .., b = .. evaluates the assignments left to right, so a later right-hand side sees the new value of an earlier column (standard SQL reads the old values). The compiler then reorders assignments to keep the standard meaning.
