Struct Group 

pub struct Group<'a> { /* private fields */ }

A zero-copy view over one repeating-group instance.

Borrows a sub-slice of the parent Message’s offset array and the raw input buffer. Field access is identical to Message: zero allocation, zero copy.

Implementations

impl<'a> Group<'a>

pub fn len(&self) -> usize

Number of fields in this group instance.

pub fn is_empty(&self) -> bool

Returns true if this group instance contains no fields.

pub fn field(&self, index: usize) -> Field<'a>

Returns the field at index. Panics if index >= self.len().

pub fn fields(&self) -> impl Iterator<Item = Field<'a>> + '_

Iterates over all fields in this group instance.

pub fn find(&self, tag: Tag) -> Option<Field<'a>>

Returns the first field with the given tag, or None.

pub fn groups(&self, spec: &GroupSpec) -> GroupIter<'a>

Return an iterator over the instances of a repeating group nested inside this group instance. Mirrors [Message::groups] exactly.

Because this group’s offsets slice is already bounded to this parent instance, the nested iterator cannot escape into sibling parent instances.

Returns an empty iterator if the nested count tag is absent or zero.

Trait Implementations

impl<'a> Clone for Group<'a>

fn clone(&self) -> Group<'a>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for Group<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
