Struct parquet::schema::types::PrimitiveTypeBuilder [−][src]
pub struct PrimitiveTypeBuilder<'a> { /* fields omitted */ }
A builder for primitive types. All attributes are optional
except the name and physical type.
Note that if not specified explicitly, Repetition::OPTIONAL
is used.
Methods
impl<'a> PrimitiveTypeBuilder<'a>
[src]
impl<'a> PrimitiveTypeBuilder<'a>
pub fn new(name: &'a str, physical_type: PhysicalType) -> Self
[src]
pub fn new(name: &'a str, physical_type: PhysicalType) -> Self
Creates new primitive type builder with provided field name and physical type.
pub fn with_repetition(self, repetition: Repetition) -> Self
[src]
pub fn with_repetition(self, repetition: Repetition) -> Self
Sets Repetition
for this field and returns itself.
pub fn with_logical_type(self, logical_type: LogicalType) -> Self
[src]
pub fn with_logical_type(self, logical_type: LogicalType) -> Self
Sets LogicalType
for this field and returns itself.
pub fn with_length(self, length: i32) -> Self
[src]
pub fn with_length(self, length: i32) -> Self
Sets type length and returns itself.
This is only applied to FIXED_LEN_BYTE_ARRAY and INT96 (INTERVAL) types, because
they maintain fixed size underlying byte array.
By default, value is 0
.
pub fn with_precision(self, precision: i32) -> Self
[src]
pub fn with_precision(self, precision: i32) -> Self
Sets precision for Parquet DECIMAL physical type and returns itself.
By default, it equals to 0
and used only for decimal context.
pub fn with_scale(self, scale: i32) -> Self
[src]
pub fn with_scale(self, scale: i32) -> Self
Sets scale for Parquet DECIMAL physical type and returns itself.
By default, it equals to 0
and used only for decimal context.
pub fn with_id(self, id: i32) -> Self
[src]
pub fn with_id(self, id: i32) -> Self
Sets optional field id and returns itself.
pub fn build(self) -> Result<Type>
[src]
pub fn build(self) -> Result<Type>
Creates a new PrimitiveType
instance from the collected attributes.
Returns Err
in case of any building conditions are not met.
