[][src]Struct diesel::sql_types::Text

pub struct 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]

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

impl<DB> FromSql<Text, DB> for *const str where
    DB: Backend + for<'a> HasRawValue<'a, RawValue = &'a [u8]>, 
[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
