Struct ImapLayer 

pub struct ImapLayer {
    pub index: LayerIndex,
}

A zero-copy view into an IMAP layer within a packet buffer.

Fields

index: LayerIndex

Implementations

impl ImapLayer

pub fn new(index: LayerIndex) -> Self

pub fn at_start(len: usize) -> Self

pub fn is_untagged(&self, buf: &[u8]) -> bool

Returns true if this is an untagged server response (starts with “* “).

pub fn is_continuation(&self, buf: &[u8]) -> bool

Returns true if this is a continuation request (starts with “+ “).

pub fn is_tagged_response(&self, buf: &[u8]) -> bool

Returns true if this is a tagged server response.

pub fn is_client_command(&self, buf: &[u8]) -> bool

Returns true if this is a client command.

pub fn tag(&self, buf: &[u8]) -> Result<String, FieldError>

Returns the tag from a tagged command or response.

Returns “*” for untagged, “+” for continuation.

Errors

Returns FieldError::InvalidValue if the payload is not valid UTF-8.

pub fn command(&self, buf: &[u8]) -> Result<String, FieldError>

Returns the command verb for a client command.

Errors

Returns FieldError::InvalidValue if the IMAP line cannot be parsed.

pub fn args(&self, buf: &[u8]) -> Result<String, FieldError>

Returns the arguments / data portion of the line.

Errors

Returns FieldError::InvalidValue if the payload is not valid UTF-8.

pub fn status(&self, buf: &[u8]) -> Result<String, FieldError>

Returns the status from a tagged or untagged server response (OK/NO/BAD/BYE/PREAUTH).

Errors

Returns FieldError::InvalidValue if the command verb is not a known status keyword.

pub fn text(&self, buf: &[u8]) -> Result<String, FieldError>

Returns the text body of a server response (after the status code).

Errors

Returns FieldError::InvalidValue if the payload is not valid UTF-8.

pub fn raw(&self, buf: &[u8]) -> String

Returns the raw payload as a string.

pub fn get_field( &self, buf: &[u8], name: &str, ) -> Option<Result<FieldValue, FieldError>>
