Struct TableRef 

pub struct TableRef {
    pub name: Cow<'static, str>,
    pub schema: Cow<'static, str>,
    pub alias: Cow<'static, str>,
}

Schema-qualified table reference (optional alias).

Fields

name: Cow<'static, str>

Table name.

schema: Cow<'static, str>

Schema name.

alias: Cow<'static, str>

Optional alias used when rendering.

Implementations

impl TableRef

pub fn new(name: impl Into<Cow<'static, str>>) -> Self

Create a new TableRef with an empty schema and alias.

pub fn full_name(&self) -> String

Return the display name: alias when present, otherwise schema.name or name.

pub fn with_alias(&self, alias: Cow<'static, str>) -> Self

Return a clone of this TableRef with the given alias set.

pub fn name<'s>(&'s self) -> &'s str

Return the table name as a borrowed &str.

pub fn schema<'s>(&'s self) -> &'s str

Return the schema name as a borrowed &str (may be empty).

pub fn alias<'s>(&'s self) -> &'s str

Return the alias as a borrowed &str (may be empty).

Trait Implementations

impl Clone for TableRef

fn clone(&self) -> TableRef

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl DataSet for &TableRef

fn qualified_columns() -> bool

where Self: Sized,

Should columns be qualified (schema.table.col)?

fn write_query( &self, writer: &dyn SqlWriter, context: &mut Context, out: &mut String, )

Render into out.

fn select<'s, Exec, Item>( &'s self, executor: &'s mut Exec, columns: impl IntoIterator<Item = Item> + Clone, condition: impl Expression, limit: Option<u32>, ) -> impl Stream<Item = Result<RowLabeled>> + 's

where Self: Sized, Exec: Executor, Item: Expression,

Fetch a SELECT query and stream labeled rows.

fn prepare<Exec, Item>( &self, executor: &mut Exec, columns: impl IntoIterator<Item = Item> + Clone, condition: impl Expression, limit: Option<u32>, ) -> impl Future<Output = Result<Query<Exec::Driver>>>

where Self: Sized, Item: Expression, Exec: Executor,

Prepare a SELECT query.

impl DataSet for TableRef

fn qualified_columns() -> bool

where Self: Sized,

Should columns be qualified (schema.table.col)?

fn write_query( &self, writer: &dyn SqlWriter, context: &mut Context, out: &mut String, )

Render into out.

fn select<'s, Exec, Item>( &'s self, executor: &'s mut Exec, columns: impl IntoIterator<Item = Item> + Clone, condition: impl Expression, limit: Option<u32>, ) -> impl Stream<Item = Result<RowLabeled>> + 's

where Self: Sized, Exec: Executor, Item: Expression,

Fetch a SELECT query and stream labeled rows.

fn prepare<Exec, Item>( &self, executor: &mut Exec, columns: impl IntoIterator<Item = Item> + Clone, condition: impl Expression, limit: Option<u32>, ) -> impl Future<Output = Result<Query<Exec::Driver>>>

where Self: Sized, Item: Expression, Exec: Executor,

Prepare a SELECT query.

impl Debug for TableRef

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

Formats the value using the given formatter.

impl Default for TableRef

fn default() -> TableRef

Returns the “default value” for a type.

impl Hash for TableRef

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for TableRef

fn eq(&self, other: &TableRef) -> 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 ToTokens for TableRef

fn to_tokens(&self, tokens: &mut TokenStream)

Write self to the given TokenStream.

fn to_token_stream(&self) -> TokenStream

Convert self directly into a TokenStream object.

fn into_token_stream(self) -> TokenStream

where Self: Sized,

Convert self directly into a TokenStream object.
