Implementations

impl DataValue

pub fn to_permutation_string(&self) -> String

Convert to String to use when permute with other Strings

pub fn to_parse_string(&self) -> String

Convert to String to use parse

pub fn format(&self, format: &str) -> Option<String>

Format this value

Support Rust-format syntax. But not support position, variable, padding with character and Pointer format ({:p}). Debug format is not supported in release build.

Examples

fn main(){
    use sbrd_gen::value::DataValue;

    assert_eq!(Some("ignore value".to_string()), DataValue::Int(12).format("ignore value"));
    assert_eq!(Some("12".to_string()), DataValue::Int(12).format("{}"));
    assert_eq!(Some("{}".to_string()), DataValue::Int(12).format("{{}}"));
    assert_eq!(Some("Rate= +12.35".to_string()), DataValue::Real(12.345).format("Rate={:+7.2}"));
    assert_eq!(Some("Rate=+012.35".to_string()), DataValue::Real(12.345).format("Rate={:+07.2}"));
    assert_eq!(Some(" aiueoあいうえお ".to_string()), DataValue::String("aiueoあいうえお".to_string()).format("{:^12}"));
    assert_eq!(Some("true    ".to_string()), DataValue::Bool(true).format("{:<8}"));
    assert_eq!(Some("null".to_string()), DataValue::Null.format("{:<10}"));
}

Trait Implementations

impl Clone for DataValue

fn clone(&self) -> DataValue

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DataValue

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DataValue

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error> where
    D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl Display for DataValue

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl FormatArgument for DataValue

fn supports_format(&self, specifier: &Specifier) -> bool

Returns true if self can be formatted using the given specifier.

fn fmt_display(&self, f: &mut Formatter<'_>) -> Result

Formats the value the way it would be formatted if it implemented std::fmt::Display.

fn fmt_debug(&self, f: &mut Formatter<'_>) -> Result

Formats the value the way it would be formatted if it implemented std::fmt::Debug.

fn fmt_octal(&self, f: &mut Formatter<'_>) -> Result

Formats the value the way it would be formatted if it implemented std::fmt::Octal.

fn fmt_lower_hex(&self, f: &mut Formatter<'_>) -> Result

Formats the value the way it would be formatted if it implemented std::fmt::LowerHex.

fn fmt_upper_hex(&self, f: &mut Formatter<'_>) -> Result

Formats the value the way it would be formatted if it implemented std::fmt::UpperHex.

fn fmt_binary(&self, f: &mut Formatter<'_>) -> Result

Formats the value the way it would be formatted if it implemented std::fmt::Binary.

fn fmt_lower_exp(&self, f: &mut Formatter<'_>) -> Result

Formats the value the way it would be formatted if it implemented std::fmt::LowerExp.

fn fmt_upper_exp(&self, f: &mut Formatter<'_>) -> Result

Formats the value the way it would be formatted if it implemented std::fmt::UpperExp.

fn to_usize(&self) -> Result<usize, ()>

Performs a type conversion into usize that might fail. Like TryInto<usize>, but does not consume self. The parser uses this to support formats whose width or precision use “dollar syntax”. For more information about these, see std::fmt. The default implementation always returns an error.
