[−][src]Struct diesel::sql_types::Text
The text SQL type.
On all backends strings must be valid UTF-8. On PostgreSQL strings must not include nul bytes.
Schema inference will treat all variants of TEXT as this type (e.g.
VARCHAR, MEDIUMTEXT, etc).

Trait Implementations
impl FromSql<Text, Sqlite> for *const str[src]
impl FromSql<Text, Sqlite> for *const strThe 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
