Implementations§

Source §

impl Ipld

Source

pub fn kind(&self) -> IpldKind

Convert from an Ipld object into its kind without any associated values.

This is intentionally not implemented via From<Ipld> to prevent accidental conversions by making it more explicit.

Source

pub fn take<'a, T>(self, index: T) -> Result<Option<Ipld>, IndexError>
where T: Into<IpldIndex<'a>>,

Destructs an ipld list or map

Source

pub fn get<'a, T>(&self, index: T) -> Result<Option<&Ipld>, IndexError>
where T: Into<IpldIndex<'a>>,

Indexes into an ipld list or map.

Source

pub fn iter(&self) -> IpldIter<'_>

Returns an iterator.

Source

pub fn references<E>(&self, set: &mut E)
where E: Extend<Cid<64>>,

Returns the references to other blocks.

impl<'de> Deserialize<'de> for Ipld

Source §

Source §

impl<'de> Deserializer<'de> for Ipld

Deserialize from an Ipld enum into a Rust type.
