Struct domain::bits::message::RecordSection [−][src]
pub struct RecordSection<'a> { /* fields omitted */ }
An iterator over one of the three record sections of a DNS message.
The iterator’s item is ParseResult<GenericRecord>
. A GenericRecord
is a record with GenericRecordData
as its data, meaning that access
to data is somewhat limited. You can, however, trade this type in for
a RecordIter
that iterates over records of a specific type through
the limit_to::<D>()
method.
RecordSection
values cannot be created directly. You can get one either
by calling the method for the section in question of a Message
value
or by proceeding from another section via its next_section()
method.

impl<'a> RecordSection<'a>
[src]
impl<'a> RecordSection<'a>
ⓘImportant traits for RecordIter<'a, D>pub fn limit_to<D: ParsedRecordData<'a>>(self) -> RecordIter<'a, D>
[src]
pub fn limit_to<D: ParsedRecordData<'a>>(self) -> RecordIter<'a, D>
Trades self
in for an iterator limited to a concrete record type.
The record type is given through its record data type. If this type is generic, it must be the variant for parsed data. Type aliases for all record data types implemented by this crate can be found in the [domain::rdata::parsed] module.
The returned limited iterator will continue at the current position
of self
. It will not start from the beginning of the section.
pub fn next_section(self) -> ParseResult<Option<Self>>
[src]
pub fn next_section(self) -> ParseResult<Option<Self>>
Returns the next section if there is one.
