pub struct ColMeta {
    pub col_id: u32,
    pub name: Option<String>,
    pub flags: u32,
    pub default: Option<Vec<u8>>,
}

Trait Implementations

impl Clone for ColMeta

fn clone(&self) -> ColMeta

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ColMeta

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

Formats the value using the given formatter.

impl PartialEq for ColMeta

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