Struct PastryClient 

pub struct PastryClient { /* private fields */ }

A client for Pastry nodes.

Implementations

impl PastryClient

pub async fn connect(address: &str) -> Result<Self>

Connects to a node in the Pastry network.

Arguments

• address - The public address of the node.

Returns

Returns a Result containing the client.

pub async fn get_kv(&mut self, key: &[u8]) -> Result<Option<Vec<u8>>>

Retrieves a value associated with the given key stored in the Pastry network.

Arguments

• key - A slice of bytes representing the key for which the value is requested.

Returns

Returns a Result which is:

• Ok(Some(Vec<u8>)) if the key exists, containing the associated value.
• Ok(None) if the key does not exist.
• Err(e) where e encapsulates any error encountered during the operation.

pub async fn set_kv( &mut self, key: &[u8], value: &[u8], ) -> Result<Option<Vec<u8>>>

Sets a value for a given key in the Pastry network.

Arguments

• key - A slice of bytes representing the key to which the value is to be associated.
• value - A slice of bytes representing the value to be set.

Returns

Returns a Result which is:

• Ok(Some(Vec<u8>)) if the key existed and the value was replaced, containing the old value.
• Ok(None) if the key did not exist and a new entry was created.
• Err(e) where e encapsulates any error encountered during the operation.

pub async fn delete_kv(&mut self, key: &[u8]) -> Result<Option<Vec<u8>>>

Deletes the value associated with the given key in the Pastry network.

Arguments

• key - A slice of bytes representing the key whose associated value is to be deleted.

Returns

Returns a Result which is:

• Ok(Some(Vec<u8>)) if the key existed and the value was successfully deleted, containing the deleted value.
• Ok(None) if the key did not exist.
• Err(e) where e encapsulates any error encountered during the operation.
