Struct Columns 

pub struct Columns { /* private fields */ }

The column metadata shared by every row of one result set.

Implementations

impl Columns

pub fn as_slice(&self) -> &[Column]

The columns, in order.

pub fn len(&self) -> usize

The number of columns.

pub fn is_empty(&self) -> bool

true if the result set has no columns.

pub fn index_of(&self, name: &str) -> Option<usize>

Resolves a column name to its index.

Uses a linear scan: result sets rarely have enough columns for a hash map allocation to pay off.
