Implementations

impl<'a> TableMeta<'a>

pub fn field_iter(&self) -> FieldIterator<'a>

returns an iterator over the fields of this table

pub fn columns_iter(&self) -> ColumnIterator<'a>

An iterator over the columns in this table

pub fn column_by_name(&self, name: &str) -> ColumnMeta<'a>

Gets the column metadata for the provided column name.

pub fn get_name(&self) -> String

Gets the name of the table.

pub fn column_count(&self) -> usize

Gets the total number of columns for the table.

pub fn column(&self, index: usize) -> ColumnMeta<'a>

Gets the column metadata for the provided index.

pub fn partition_key_count(&self) -> usize

Gets the number of columns for the table’s partition key.

pub fn partition_key(&self, index: usize) -> Option<ColumnMeta<'a>>

Gets the partition key column metadata for the provided index.

pub fn clustering_key_count(&self) -> usize

Gets the number of columns for the table’s clustering key

pub fn cluster_key(&self, index: usize) -> Option<ColumnMeta<'a>>

Gets the clustering key column metadata for the provided index.

pub fn field_by_name(&self, name: &str) -> Option<Value<'a>>

Gets a metadata field for the provided name. Metadata fields allow direct access to the column data found in the underlying “tables” metadata table.
