Struct Context 

pub struct Context {
    pub counter: u32,
    pub fragment: Fragment,
    pub table_ref: TableRef,
    pub qualify_columns: bool,
    pub quote_identifiers: bool,
}

Holds state during SQL generation, including current fragment, table context, and formatting options.

Fields

counter: u32

fragment: Fragment

table_ref: TableRef

qualify_columns: bool

quote_identifiers: bool

Implementations

impl Context

pub const fn new(fragment: Fragment, qualify_columns: bool) -> Self

Creates a new generation context for a specific fragment.

pub const fn empty() -> Self

Creates an empty context with no special configuration.

pub const fn fragment(fragment: Fragment) -> Self

Creates a context for a specific SQL fragment.

pub const fn qualify(qualify_columns: bool) -> Self

Creates a context that enforces identifying columns with their table name.

pub const fn qualify_with(table: Cow<'static, str>) -> Self

Creates a context qualified with a specific table name.

pub const fn update_from(&mut self, context: &Context)

pub fn switch_fragment<'s>( &'s mut self, fragment: Fragment, ) -> ContextUpdater<'s>

pub fn switch_table<'s>(&'s mut self, table_ref: TableRef) -> ContextUpdater<'s>

Trait Implementations

impl Clone for Context

fn clone(&self) -> Context

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Context

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

Formats the value using the given formatter.

impl Default for Context

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for Context

fn eq(&self, other: &Context) -> 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.
