Implementations§

source§

impl<'a> FormatOptions<'a>

source

pub const fn new() -> FormatOptions<'a>

source

pub const fn with_display_error(self, safe: bool) -> FormatOptions<'a>

source

pub const fn with_null(self, null: &'a str) -> FormatOptions<'a>

Overrides the string used to represent a null

Defaults to ""

source
