Type Definition diesel::sql_types::VarChar
[−]
[src]
type VarChar = Text;
The SQL VARCHAR type
This type is generally interchangeable with TEXT, so Diesel has this as an
alias rather than a separate type (Diesel does not currently support
implicit coercions).
One notable exception to this is with arrays on PG. TEXT[] cannot be
coerced to VARCHAR[]. It is recommended that you always use TEXT[] if
you need a string array on PG.
Trait Implementations
impl FromSql<VarChar, Sqlite> for *const str[src]
The returned pointer is only valid for the lifetime to the argument of
from_sql. This impl is intended for uses where you want to write a new
impl in terms of String, but don't want to allocate. We have to return a
raw pointer instead of a reference with a lifetime due to the structure of
FromSql
