unknown display hint: "ipv4"

[bck01215]

Following the logging for xdp guide I get this error:

error: could not parse the format string: unknown display hint: "ipv4"
  --> src/main.rs:68:9
   |
68 | ...   "SRC IP: {:ipv4}, SRC PORT: {}", source_addr, sour...

Fix:

    info!(
        &ctx,
        "SRC IP: {}, SRC PORT: {}", source_addr, source_port
    );

Not sure if the display hint adds value. This is my cargo.toml

[package]
name = "learning-ebpf"
version = "0.1.0"
edition = "2021"

[dependencies]
aya-bpf = { git = "https://github.com/aya-rs/aya", branch = "main" }
aya-log-ebpf = { git = "https://github.com/aya-rs/aya", branch = "main" }
learning-common = { path = "../learning-common" }
network-types = "0.0.4"

[[bin]]
name = "learning"
path = "src/main.rs"

[profile.dev]
opt-level = 3
debug = false
debug-assertions = false
overflow-checks = false
lto = true
panic = "abort"
incremental = false
codegen-units = 1
rpath = false

[profile.release]
lto = true
panic = "abort"
codegen-units = 1

[workspace]
members = []

It looks like it should come from aya-log-ebpf but I don't know how.

This is being worked on in aya-rs/book#118. Closing this, but please reopen.

The display hint should be {:i}.
