Enum git2::AttrValue[−][src]

pub enum AttrValue<'string> {
    True,
    False,
    String(&'string str),
    Bytes(&'string [u8]),
    Unspecified,
}

Expand description

All possible states of an attribute.

This enum is used to interpret the value returned by Repository::get_attr and Repository::get_attr_bytes.

Variants

True

The attribute is set to true.

False

The attribute is unset (set to false).

String(&'string str)

The attribute is set to a valid UTF-8 string.

Tuple Fields of String

0: &'string str

Bytes(&'string [u8])

The attribute is set to a string that might not be valid UTF-8.

Tuple Fields of Bytes

0: &'string [u8]

Unspecified

The attribute is not specified.

Implementations

impl<'string> AttrValue<'string>

pub fn from_string(value: Option<&'string str>) -> Self

Returns the state of an attribute by inspecting its value by a string.

This function always returns AttrValue::String and never returns AttrValue::Bytes when the attribute is set to a string.

pub fn from_bytes(value: Option<&'string [u8 ]>) -> Self

Returns the state of an attribute by inspecting its value by a byte slice.

This function will perform UTF-8 validation when the attribute is set to a string, returns AttrValue::String if it’s valid UTF-8 and AttrValue::Bytes otherwise.

pub fn always_bytes(value: Option<&'string [u8 ]>) -> Self

Returns the state of an attribute just like AttrValue::from_bytes, but skips UTF-8 validation and always returns AttrValue::Bytes when it’s set to a string.
