pub fn empty() -> Self

pub fn try_merge( schemas: impl IntoIterator<Item = Self>, ) -> QuillSQLResult<Self>

pub fn project(&self, indices: &[usize]) -> QuillSQLResult<Schema>

pub fn column_with_name( &self, relation: Option<&TableReference>, name: &str, ) -> QuillSQLResult<ColumnRef>

pub fn column_with_index(&self, index: usize) -> QuillSQLResult<ColumnRef>

pub fn index_of( &self, relation: Option<&TableReference>, name: &str, ) -> QuillSQLResult<usize>

Find the index of the column with the given name.

pub fn column_count(&self) -> usize

Trait Implementations

impl Clone for Schema

fn clone(&self) -> Schema

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Schema

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

Formats the value using the given formatter.

impl PartialEq for Schema

fn eq(&self, other: &Schema) -> 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 Eq for Schema
