[−][src]Struct parquet::schema::types::ColumnDescriptor
A descriptor for leaf-level primitive columns. This encapsulates information such as definition and repetition levels and is used to re-assemble nested data.
Methods
impl ColumnDescriptor[src]
impl ColumnDescriptorpub fn new(
primitive_type: TypePtr,
root_type: Option<TypePtr>,
max_def_level: i16,
max_rep_level: i16,
path: ColumnPath
) -> Self[src]
pub fn new(
primitive_type: TypePtr,
root_type: Option<TypePtr>,
max_def_level: i16,
max_rep_level: i16,
path: ColumnPath
) -> SelfCreates new descriptor for leaf-level column.
pub fn max_def_level(&self) -> i16[src]
pub fn max_def_level(&self) -> i16Returns maximum definition level for this column.
pub fn max_rep_level(&self) -> i16[src]
pub fn max_rep_level(&self) -> i16Returns maximum repetition level for this column.
pub fn path(&self) -> &ColumnPath[src]
pub fn path(&self) -> &ColumnPathReturns ColumnPath for this column.
pub fn self_type(&self) -> &Type[src]
pub fn self_type(&self) -> &TypeReturns self type Type for this leaf column.
pub fn root_type(&self) -> &Type[src]
pub fn root_type(&self) -> &TypeReturns root Type (most top-level parent field) for
this leaf column.
pub fn name(&self) -> &str[src]
pub fn name(&self) -> &strReturns column name.
pub fn logical_type(&self) -> LogicalType[src]
pub fn logical_type(&self) -> LogicalTypeReturns LogicalType for this column.
pub fn physical_type(&self) -> PhysicalType[src]
pub fn physical_type(&self) -> PhysicalTypeReturns physical type for this column. Note that it will panic if called on a non-primitive type.
pub fn type_length(&self) -> i32[src]
pub fn type_length(&self) -> i32Returns type length for this column. Note that it will panic if called on a non-primitive type.
pub fn type_precision(&self) -> i32[src]
pub fn type_precision(&self) -> i32Returns type precision for this column. Note that it will panic if called on a non-primitive type.
pub fn type_scale(&self) -> i32[src]
pub fn type_scale(&self) -> i32Returns type scale for this column. Note that it will panic if called on a non-primitive type.
