Trait parse_mediawiki_sql::from_sql::FromSql

pub trait FromSql<'a>: Sized {
    fn from_sql(s: &'a [u8]) -> IResult<'a, Self>;
}

Trait for converting from the SQL syntax for a simple type (anything other than a tuple) to a Rust type, which can borrow from the string or not. Used by schemas::FromSqlTuple.

Required methods

fn from_sql(s: &'a [u8]) -> IResult<'a, Self>

Implementations on Foreign Types

impl<'a> FromSql<'a> for bool

Parses a bool from 1 or 0.

fn from_sql(s: &'a [u8]) -> IResult<'a, i32>

impl<'a> FromSql<'a> for i64

fn from_sql(s: &'a [u8]) -> IResult<'a, i64>

impl<'a> FromSql<'a> for f32

Matches a float literal with recognize_float and parses it as a f32.

fn from_sql(s: &'a [u8]) -> IResult<'a, f32>

impl<'a> FromSql<'a> for f64

Matches a float literal with recognize_float and parses it as a f64.

fn from_sql(s: &'a [u8]) -> IResult<'a, f64>

impl<'a> FromSql<'a> for &'a [u8]

Used for byte strings that have no escape sequences.

fn from_sql(s: &'a [u8]) -> IResult<'a, Self>

impl<'a> FromSql<'a> for &'a str

Used for types represented as strings without escape sequences. For instance, Timestamps matches the regex ^[0-9: -]+$ and thus never has any escape sequences.

fn from_sql(s: &'a [u8]) -> IResult<'a, Self>

impl<'a> FromSql<'a> for String

Use this for string types that require unescaping and are guaranteed to be valid UTF-8, like page titles.

fn from_sql(s: &'a [u8]) -> IResult<'a, Self>

impl<'a> FromSql<'a> for Vec<u8>

Used for “strings” that sometimes contain invalid UTF-8, like the cl_sortkey field in the categorylinks table, which is truncated to 230 bits, sometimes in the middle of a UTF-8 sequence.

fn from_sql(s: &'a [u8]) -> IResult<'a, Self>

impl<'a> FromSql<'a> for ()

fn from_sql(s: &'a [u8]) -> IResult<'a, Self>

impl<'a, T> FromSql<'a> for Option<T> where
    T: FromSql<'a>,

fn from_sql(s: &'a [u8]) -> IResult<'a, Self>

impl<'a> FromSql<'a> for NotNan<f32>

Parses an f32 and wraps it with NotNan::unchecked_new.

Safety

This will never accidentally wrap a NaN because nom’s recognize_float doesn’t include a representation of NaN.

fn from_sql(s: &'a [u8]) -> IResult<'a, NotNan<f32>>

impl<'a> FromSql<'a> for NotNan<f64>

Parses an f64 and wraps it with NotNan::unchecked_new.

Safety

This will never accidentally wrap a NaN because nom’s recognize_float doesn’t include a representation of NaN.
