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.
Creates new primitive type builder with provided field name and physical type.
Sets Repetition
for this field and returns itself.
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
.
Sets precision for Parquet DECIMAL physical type and returns itself.
By default, it equals to 0
and used only for decimal context.
Sets scale for Parquet DECIMAL physical type and returns itself.
By default, it equals to 0
and used only for decimal context.
Sets optional field id and returns itself.
Creates a new PrimitiveType
instance from the collected attributes.
Returns Err
in case of any building conditions are not met.

Create an error for a missing method specialization. Defaults to panicking with type, trait & method names. S
is the encoder/decoder state type, T
is the type being encoded/decoded, and the arguments are the names of the trait and method that should've been overridden. Read more
