[−][src]Struct parquet::schema::types::SchemaDescriptor
A schema descriptor. This encapsulates the top-level schemas for all the columns, as well as all descriptors for all the primitive columns.
Implementations
impl SchemaDescriptor[src]
pub fn new(tp: TypePtr) -> Self[src]
Creates new schema descriptor from Parquet schema.
pub fn column(&self, i: usize) -> ColumnDescPtr[src]
Returns ColumnDescriptor for a field position.
pub fn columns(&self) -> &[ColumnDescPtr][src]
Returns slice of ColumnDescriptor.
pub fn num_columns(&self) -> usize[src]
Returns number of leaf-level columns.
pub fn get_column_root(&self, i: usize) -> &Type[src]
Returns column root Type for a field position.
pub fn get_column_root_ptr(&self, i: usize) -> TypePtr[src]
Returns column root Type pointer for a field
position.
pub fn root_schema(&self) -> &Type[src]
Returns schema as Type.
pub fn name(&self) -> &str[src]
Returns schema name.
