Enum Content

enum Content<'de, 'a> {
    Input(&'de str),
    Slice(&'a str),
    Owned(String, usize),
}

A version of Cow that can borrow from two different buffers, one of them is a deserializer input, and conceptually contains only part of owned data.

Lifetimes

• 'de – lifetime of the data that deserializer borrow from the parsed input
• 'a – lifetime of the data that owned by a deserializer

Variants

Input(&'de str)

An input borrowed from the parsed data

Slice(&'a str)

An input borrowed from the buffer owned by another deserializer

Owned(String, usize)

An input taken from an external deserializer, owned by that deserializer. Only part of this data, located after offset represented by usize, used to deserialize data, the other is a garbage that can’t be dropped because we do not want to make reallocations if they will not required.

Implementations

impl<'de, 'a> Content<'de, 'a>

fn as_str(&self) -> &str

Returns string representation of the content

fn deserialize_all<V>(self, visitor: V) -> Result<V::Value, DeError>

where V: Visitor<'de>,

Supply to the visitor a borrowed string, a string slice, or an owned string depending on the kind of input. Unlike Self::deserialize_item, the whole Self::Owned string will be passed to the visitor.

Calls

• visitor.visit_borrowed_str if data borrowed from the input
• visitor.visit_str if data borrowed from another source
• visitor.visit_string if data owned by this type

fn deserialize_item<V>(self, visitor: V) -> Result<V::Value, DeError>

where V: Visitor<'de>,

Supply to the visitor a borrowed string, a string slice, or an owned string depending on the kind of input. Unlike Self::deserialize_all, only part of Self::Owned string will be passed to the visitor.

Calls

• visitor.visit_borrowed_str if data borrowed from the input
• visitor.visit_str if data borrowed from another source
• visitor.visit_string if data owned by this type
