Enum DeltaOp 

pub enum DeltaOp {
    Add {
        r: Ref,
        parent: Ref,
        pos: Option<u32>,
        role: Role,
        label: String,
        ops: BTreeSet<Op>,
        attrs: BTreeMap<String, String>,
    },
    Remove {
        r: Ref,
    },
    Update {
        r: Ref,
        attrs: BTreeMap<String, String>,
    },
    Move {
        r: Ref,
        parent: Ref,
        pos: Option<u32>,
    },
    Replace {
        r: Ref,
        subtree: Vec<Node>,
    },
}

One delta operation.

Variants

Add

Insert a new leaf node under parent at pos (or end if None). parent == Ref::ROOT means root level.

Fields

r: Ref

parent: Ref

pos: Option<u32>

role: Role

label: String

ops: BTreeSet<Op>

attrs: BTreeMap<String, String>

Remove

Remove the subtree rooted at r.

Fields

r: Ref

Update

Replace the attribute map at r (per docs/codes.md, Update is attribute-only; for role/label/ops changes use DeltaOp::Replace).

Fields

r: Ref

attrs: BTreeMap<String, String>

Move

Reparent or reorder r to parent at pos.

Fields

r: Ref

parent: Ref

pos: Option<u32>

Replace

Blow away the subtree at r and install subtree in its place. subtree[0].r == r; the wire-form indents these lines under the *<ref> header.

Fields

r: Ref

subtree: Vec<Node>

Implementations

impl DeltaOp

pub fn target(&self) -> Ref

The ref this op operates on.

Trait Implementations

impl Clone for DeltaOp

fn clone(&self) -> DeltaOp

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DeltaOp

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

Formats the value using the given formatter.

impl PartialEq for DeltaOp

fn eq(&self, other: &DeltaOp) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
