Struct SqlQueryResultMetadata 

pub struct SqlQueryResultMetadata {
    pub columns: Vec<Column>,
}

metadata of result sets.

Fields

columns: Vec<Column>

the column information.

Implementations

impl SqlQueryResultMetadata

See SqlQueryResult::get_metadata().

pub fn columns(&self) -> &Vec<SqlColumn>

Returns the column information of the query.

Examples

use tsubakuro_rust_core::prelude::*;

fn example(metadata: &SqlQueryResultMetadata) {
    let columns = metadata.columns();

    for column in columns {
        let column_name = column.name();
        let atom_type = column.atom_type();
    }
}

Trait Implementations

impl Clone for ResultSetMetadata

fn clone(&self) -> ResultSetMetadata

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ResultSetMetadata

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

Formats the value using the given formatter.

impl Default for ResultSetMetadata

fn default() -> Self

Returns the “default value” for a type.

impl Message for ResultSetMetadata

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for ResultSetMetadata

fn eq(&self, other: &ResultSetMetadata) -> 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.
