Struct Column 

pub struct Column {
    pub value: SqlType,
    pub raw_type: u32,
    pub name: Arc<str>,
}

Fields

value: SqlType

raw_type: u32

name: Arc<str>

Column name/alias. Arc<str> so the driver can clone it into every row with just a refcount bump — the name is constant across a result set, and cloning a String per column per row was the dominant decode allocation.

Implementations

impl Column

pub fn new(name: impl Into<Arc<str>>, raw_type: u32, value: SqlType) -> Self
