[−][src]Struct parquet::schema::types::GroupTypeBuilder
A builder for group types. All attributes are optional except the name.
Note that if not specified explicitly, None
is used as the repetition of the group,
which means it is a root (message) type.
Methods
impl<'a> GroupTypeBuilder<'a>
[src]
impl<'a> GroupTypeBuilder<'a>
pub fn new(name: &'a str) -> Self
[src]
pub fn new(name: &'a str) -> Self
Creates new group type builder with provided field name.
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_fields(self, fields: &mut Vec<TypePtr>) -> Self
[src]
pub fn with_fields(self, fields: &mut Vec<TypePtr>) -> Self
Sets a list of fields that should be child nodes of this field. Returns updated self.
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 GroupType
instance from the gathered attributes.
