Struct aws_sdk_datasync::types::HdfsNameNode

#[non_exhaustive]
pub struct HdfsNameNode {
    pub hostname: Option<String>,
    pub port: Option<i32>,
}

The NameNode of the Hadoop Distributed File System (HDFS). The NameNode manages the file system's namespace. The NameNode performs operations such as opening, closing, and renaming files and directories. The NameNode contains the information to map blocks of data to the DataNodes.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

hostname: Option<String>

The hostname of the NameNode in the HDFS cluster. This value is the IP address or Domain Name Service (DNS) name of the NameNode. An agent that's installed on-premises uses this hostname to communicate with the NameNode in the network.

port: Option<i32>

The port that the NameNode uses to listen to client requests.

Implementations

impl HdfsNameNode

pub fn hostname(&self) -> Option<&str>

The hostname of the NameNode in the HDFS cluster. This value is the IP address or Domain Name Service (DNS) name of the NameNode. An agent that's installed on-premises uses this hostname to communicate with the NameNode in the network.

pub fn port(&self) -> Option<i32>

The port that the NameNode uses to listen to client requests.

impl HdfsNameNode

pub fn builder() -> HdfsNameNodeBuilder

Creates a new builder-style object to manufacture HdfsNameNode.

Trait Implementations

impl Clone for HdfsNameNode

fn clone(&self) -> HdfsNameNode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for HdfsNameNode

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

Formats the value using the given formatter.

impl PartialEq<HdfsNameNode> for HdfsNameNode

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

This method tests for self and other values to be equal, and is used by ==.

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

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