Struct PragmaText 

pub struct PragmaText<'a>(/* private fields */);

Available on crate feature __sqlite-shared only.

Text written as a single-quoted SQL string with embedded quotes doubled, such as 'UTF-16le'.

Text holding a NUL byte fails with Error::InvalidCString before reaching SQLite.

use diesel::sqlite::pragma::{
    ConnectionPragma, PerConnection, Pragma, PragmaText, ReadPragma, WritePragma,
};

struct Encoding;

impl Pragma for Encoding {
    const NAME: &'static str = "encoding";
    type Scope = PerConnection;
}

impl ReadPragma for Encoding {
    type SqlType = Text;
}

impl WritePragma for Encoding {
    type Argument<'a> = PragmaText<'a>;
}

let conn = &mut SqliteConnection::establish(":memory:").unwrap();
// SQLite only changes the encoding before anything is written.
Encoding::set("UTF-16le", conn)?;
assert_eq!("UTF-16le", Encoding::get::<String>(conn)?);
