Struct FetchArgs 

pub struct FetchArgs {
    pub hash: String,
    pub output: PathBuf,
    pub namespace: Option<u64>,
    pub common: ClientFetchArgs,
}

Arguments for decdn fetch — one blob to a file, atop ClientFetchArgs.

Fields

hash: String

BLAKE3 hash of the blob to fetch: 64 hex chars (optional 0x or b3: prefix — the b3: form is what bundle manifests carry).

output: PathBuf

Destination path for the fetched blob. Written atomically (temp-in-dir then rename); an existing file is replaced.

namespace: Option<u64>

Namespace the content is published under (ADR 002 § Retrieval by namespace). When set, the serving node routes a cache-miss origin pull to that namespace’s DAO-authorized origins. Absent => no namespace: no routing to a namespace’s authorized origin set — served from cache, from peers, or from the serving node’s OWN configured origin, which stays a serve target either way (namespace_id is a routing hint, not a serve gate — ADR 002).

common: ClientFetchArgs

Retrieval flags shared with decdn bundle pull: peer discovery, chain and payment-pool coordinates, the source cap and the give-up limit.

Trait Implementations

impl Args for FetchArgs

fn group_id() -> Option<Id>

Report the ArgGroup::id for this set of arguments

fn augment_args<'b>(__clap_app: Command) -> Command

Append to Command so it can instantiate Self via FromArgMatches::from_arg_matches_mut

fn augment_args_for_update<'b>(__clap_app: Command) -> Command

Append to Command so it can instantiate self via FromArgMatches::update_from_arg_matches_mut

impl Clone for FetchArgs

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FetchArgs

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

Formats the value using the given formatter.

impl FromArgMatches for FetchArgs

fn from_arg_matches(__clap_arg_matches: &ArgMatches) -> Result<Self, Error>

Instantiate Self from ArgMatches, parsing the arguments as needed.

fn from_arg_matches_mut( __clap_arg_matches: &mut ArgMatches, ) -> Result<Self, Error>

Instantiate Self from ArgMatches, parsing the arguments as needed.

fn update_from_arg_matches( &mut self, __clap_arg_matches: &ArgMatches, ) -> Result<(), Error>

Assign values from ArgMatches to self.

fn update_from_arg_matches_mut( &mut self, __clap_arg_matches: &mut ArgMatches, ) -> Result<(), Error>

Assign values from ArgMatches to self.
