Implementations

impl SourceExpr

pub fn get_db_table(&self) -> Option<&DbTable>

pub fn table_name(&self) -> &str

pub fn table_type(&self) -> StTableType

pub fn table_access(&self) -> StAccess

pub fn get_column_by_field<'a>( &'a self, field: &'a FieldName ) -> Option<&Column>

Check if the name of the FieldName exist on this SourceExpr

Warning: It ignores the table_name

Trait Implementations

impl Clone for SourceExpr

fn clone(&self) -> SourceExpr

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SourceExpr

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

Formats the value using the given formatter.

impl Display for SourceExpr

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

Formats the value using the given formatter.

impl From<&SourceExpr> for DbTable

fn from(value: &SourceExpr) -> Self

Converts to this type from the input type.

impl From<DbTable> for SourceExpr

fn from(original: DbTable) -> SourceExpr

Converts to this type from the input type.

impl From<MemTable> for SourceExpr

fn from(original: MemTable) -> SourceExpr

Converts to this type from the input type.

impl From<SourceExpr> for Table

fn from(value: SourceExpr) -> Self

Converts to this type from the input type.

impl From<Table> for SourceExpr

fn from(value: Table) -> Self

Converts to this type from the input type.

impl Ord for SourceExpr

fn cmp(&self, other: &SourceExpr) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for SourceExpr

fn eq(&self, other: &SourceExpr) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for SourceExpr

fn partial_cmp(&self, other: &SourceExpr) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Relation for SourceExpr

fn head(&self) -> &Header

fn row_count(&self) -> RowCount

Specify the size in rows of the Relation.

impl Eq for SourceExpr

impl StructuralEq for SourceExpr
