Contains information needed to serialize a row.
Implementations§
Source§impl<'a> RowSerializationContext<'a>
impl<'a> RowSerializationContext<'a>
Sourcepub fn from_prepared(
prepared: &'a PreparedMetadata,
) -> RowSerializationContext<'a>
pub fn from_prepared( prepared: &'a PreparedMetadata, ) -> RowSerializationContext<'a>
Creates the serialization context from prepared statement metadata.
Sourcepub const fn empty() -> RowSerializationContext<'a>
pub const fn empty() -> RowSerializationContext<'a>
Constructs an empty RowSerializationContext, as if for a statement
with no bind markers.
Sourcepub fn columns(&self) -> &'a [ColumnSpec]
pub fn columns(&self) -> &'a [ColumnSpec]
Returns column/bind marker specifications for given query.
Sourcepub fn column_by_name(&self, target: &str) -> Option<&ColumnSpec>
pub fn column_by_name(&self, target: &str) -> Option<&ColumnSpec>
Looks up and returns a column/bind marker by name.
