Struct Field 

pub struct Field {
    pub name: &'static str,
    pub columns: &'static [ColumnSpec],
    pub nullable: bool,
    pub parse_text: fn(&str) -> Option<Result<SqlValue, FieldError>>,
    pub handed_back: fn() -> bool,
}

Fields

name: &'static str

columns: &'static [ColumnSpec]

nullable: bool

parse_text: fn(&str) -> Option<Result<SqlValue, FieldError>>

handed_back: fn() -> bool

Whether the server can read the stored value back, so an edit left blank keeps it.

Implementations

impl Field

pub const fn new( name: &'static str, columns: &'static [ColumnSpec], nullable: bool, ) -> Self

pub const fn handed_back_by(self, handed_back: fn() -> bool) -> Self

pub const fn parsed_by( self, parse_text: fn(&str) -> Option<Result<SqlValue, FieldError>>, ) -> Self

A list filter reads the text by the column’s type only when this gives None, no reader.

Trait Implementations

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