Enum Event 

#[non_exhaustive]
pub enum Event<'p> {
    PartStart(PartHead<'p>),
    Data(&'p [u8]),
    PartEnd(PartSummary),
    End,
    NeedInput,
}

What the parser found.

Per part the order is always PartStart, any number of Data (none for an empty part), PartEnd. A Data slice is never empty. After the last part comes End. NeedInput can appear anywhere between.

Debug prints the length of Data, never the bytes.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

PartStart(PartHead<'p>)

A part’s headers were read and checked.

Data(&'p [u8])

Bytes of the current part’s data.

PartEnd(PartSummary)

The current part ended.

End

The close delimiter was read: the form is complete.

NeedInput

Every byte given was consumed; give more.
