Struct mz_interchange::protobuf::DecodedDescriptors

pub struct DecodedDescriptors {
    message_descriptor: MessageDescriptor,
    columns: Vec<(ColumnName, ColumnType)>,
    message_name: String,
}

A decoded description of the schema of a Protobuf message.

Fields

message_descriptor: MessageDescriptor

columns: Vec<(ColumnName, ColumnType)>

message_name: String

Implementations

impl DecodedDescriptors

pub fn from_bytes(bytes: &[u8], message_name: String) -> Result<Self, Error>

Builds a DecodedDescriptors from an encoded FileDescriptorSet and the fully qualified name of a message inside that file descriptor set.

pub fn columns(&self) -> &[(ColumnName, ColumnType)]

Describes the columns in the message.

In other words, the return value describes the shape of the rows that will be produced by a Decoder constructed from this DecodedDescriptors.

Trait Implementations

impl Debug for DecodedDescriptors

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for DecodedDescriptors

fn eq(&self, other: &DecodedDescriptors) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
