Struct ModelColumn 

#[non_exhaustive]
pub struct ModelColumn {
    pub name: &'static str,
    pub rust_type: &'static str,
    pub kind: ColumnKind,
    pub nullable: bool,
    pub default: Option<&'static str>,
    pub references: Option<&'static str>,
}

One column of a model, as the derive describes it.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

name: &'static str

The column’s name.

rust_type: &'static str

The field’s Rust type, as written.

kind: ColumnKind

What kind of column the type fills.

nullable: bool

Whether the field is an Option.

default: Option<&'static str>

The SQL default from #[model(default = "…")], if any.

references: Option<&'static str>

The table from #[model(references = "…")], if any.

Implementations

impl ModelColumn

pub const fn new( name: &'static str, rust_type: &'static str, kind: ColumnKind, nullable: bool, ) -> Self

Describes one column.

pub const fn default_sql(self, sql: &'static str) -> Self

Sets the column’s SQL default (#[model(default = "0")]).

pub const fn references(self, table: &'static str) -> Self

Sets the table the column points at (#[model(references = "users")]).

Trait Implementations

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

Performs copy-assignment from source.

impl Debug for ModelColumn

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